ITS320 Module 2 Option 1 Creating a Python Application for string validation

Option #1: Creating a Python Application
Python has built-in string validation methods for basic data. It can check if a string is composed of alphabetical characters, alphanumeric characters, digits, etc.
str.isalnum() This method checks if all the characters of a string are alphanumeric (a-z, A-Z and 0-9).
>>> print 'ab123'.isalnum()
True
>>> print 'ab123#'.isalnum()
False
str.isalpha() This method checks if all the characters of a string are alphabetical (a-z and A-Z).
>>> print 'abcD'.isalpha()
True
>>> print 'abcd1'.isalpha()
False
str.isdigit() This method checks if all the characters of a string are digits (0-9).
>>> print '1234'.isdigit()
True
>>> print '123edsd'.isdigit()
False
str.islower() This method checks if all the characters of a string are lowercase characters (a-z).
>>> print 'abcd123#'.islower()
True
>>> print 'Abcd123#'.islower()
FalseSAMPLE
str.isupper() This method checks if all the characters of a string are uppercase characters (A-Z).
>>> print 'ABCD123#'.isupper()
True
>>> print 'Abcd123#'.isupper()
False

Assignment Instructions:
Write a Python program that performs the following tasks:
1. Read from the console an arbitrary string S of length less than 50 characters.

CIS115 Week 1 Lab Building a Registration Form and Pay Calculator in Python

CIS115 Week 1 Lab Overview

Title of Lab: Building a Registration Form and Pay Calculator in Python

Summary – Part 1
Create a program that allows a student to complete a registration form and displays a completion message that includes the user's full name and a temporary password.

Summary – Part 2
Create a program that calculates a user's weekly gross and take-home pay.

Deliverables
• 2 source code Python files.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps
Part 1 – Registration Form

Sample Output:
Registration Form
First Name: Eric
Last Name: Idle
Birth Year: 1934
Welcome Eric Idle!
Your Registration is complete.
Your temporary password is: Eric*1934

Specifications:
• The user's full name consists of the user's first name, a space, and the user's last name.
• The temporary password consists of the user's first name, an asterisk (*), and the user's birth year.
• Assume the user will enter valid data.

INPUT  PROCESSING         OUTPUT
first_name password=first_name + "*" + str(birth_year) password
last_name
birth_year

Part 2 – Pay Calculator

Sample Output:
Pay Check Calculator
Hours Worked: 35
Hourly Pay Rate: 14.50
Gross Pay: 507.5
Tax Rate: 18
Tax Amount: 91.35
Take Home Pay: 416.15

• The formula for calculating gross pay is:
 o gross pay = hours worked * hourly rate
• The formula for calculating tax amount is:
 o tax amount = gross pay * (tax rate / 100)
• The formula for calculating take home pay is:
 o take home pay = gross pay - tax amount
• The tax rate should be 18%, but the program should store the tax rate in a variable so that you can easily change the tax rate later, just by changing the value that's stored in the variable.
• The program should accept decimal entries like 35.5 and 14.25.
• Assume the user will enter valid data.
• The program should round the results to a maximum of two decimal places.

INPUT  PROCESSING           OUTPUT
hours  gross_pay = round(hours * pay_rate, 2)    gross_pay
pay_rate tax_rate = 18          tax_rate
   tax_amount = round(gross_pay * (tax_rate / 100), 2) tax_amount
   take_home_pay = round(gross_pay - tax_amount, 2) take_home_pay

10 |    10 #   20 #   30 #   40 #   50 #   60 #   70 #   80 #   90 #  100 #

Hints:
• The outer loop will start each new row.
• The inner loop will control the display of each column in the row.
• Note that to keep the numbers right-aligned, there are different amounts of space before single digit numbers (those less than 10), double digit numbers (those between 10-99), and triple digit numbers (100).
• The row labels can be added to your inner loop (note that there are different amounts of space required after the number in the row labels.
• The column labels should use a separate loop(s) that run before the main outer loop.
• You can continue printing on the same line using end="" in your print statement. This will come in handy if you want to print several things on one line inside a loop. For example, assuming the value of name is Ada, the following will print "Hello Ada" on one line:
print("hello ", end="")
print(name, end="")

Tips:
• Start early!
• Do the basic table first without worrying about spacing or lining things up, and don't include row or column headings (add those later).
• Once you get the numbers in the correct position, think about adding the proper amount of space before each number to line things up.
• Once the columns line up, add the #/space for even/odd numbers.
• Once the basic table is working, then add the row and column headings, and finally the main title.
• Test as you go!

Summary
Create a program that will allow a user to add, list, and delete items from a shopping list.

Deliverables
• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps
The program should be modular. For example, you will want to have an add_item(shopping_list) function, a delete_item(shopping_list) function, a display_list(shopping_list) function, a display_menu() function, and a main().

Sample Output:
Welcome to the program!
1. Add an item
2. List all items
3. Delete an item
4. Exit

Enter a menu option: 2
1 : bananas
2 : apples

Enter a menu option: 1
Please enter the item: pears
pears was added to the shopping list

Enter a menu option: 2
1 : bananas
2 : apples
3 : pears

Enter a menu option: 3
Which number to delete: 3
pears was deleted

Enter a menu option: 2
1 : bananas
2 : apples

Enter a menu option: 4
have a great day!

Specifications:
• The program should start with 2 items in the shopping list.
• Don't forget to include at the end of the program the code:
 o if __name__ == "__main__":
   main();
• Use this code for the delete_item(shopping_list) function:
 def delete_item(shopping_list):
    number=int(input("Which number to delete: "))
    if number<1 or number>len(shopping_list):
        print("Invalid number\n")
    else:
        item=shopping_list.pop(number-1)
        print(item," was deleted\n")
    print()

CYB/130 Week 3 Python LAB 4.16: Output range with increment of 10

Write a program whose input is two integers. Output the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer.

Ex: If the input is:
-15
30
the output is:
-15 -5 5 15 25

Ex: If the second integer is less than the first as in:
20
5
the output is:
Second integer can't be less than the first.

For coding simplicity, output a space after every integer, including the last.

CYB/130 Week 3 Python LAB 4.14 LAB: Count input length without spaces, periods, or commas

Given a line of text as input, output the number of characters excluding spaces, periods, or commas.

Ex: If the input is:
Listen, Mr. Jones, calm down.
the output is:
21

Note: Account for all characters that aren't spaces, periods, or commas (Ex: "r", "2", "!").

CYB/130 Week 4 Python LAB 5.18: Miles to track laps
One lap around a standard high-school running track is exactly 0.25 miles. Write the function miles_to_laps() that takes a number of miles as an argument and returns the number of laps. Complete the program to output the number of laps.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
1.5
the output is:
6.00

Ex: If the input is:
2.2
the output is:
8.80

Your program must define and call the following function:
def miles_to_laps(user_miles)

CYB/130 Week 4 Python LAB 5.19: Driving costs - functions
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:
20.0
3.1599
the output is:
1.58
7.90
63.20

Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.

Ex: If the function is called with:
50  20.0  3.1599
the function returns:
7.89975

def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)
Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
Note: This is a lab from a previous chapter that now requires the use of a function.
