Learning Objectives
- Use the while loop to repeat action an unknown number of times
- Practice input() statement inside the loop
- Learn complex string comparison condition inside the the while loop
- Create a function with a given name and parameter and given return values
- Use if/else statements inside the function to achieve different return statements by condition
- Use int() integer conversion function to have the number from string
Instructions
A keyboard can be really tricky! You try to enter a number but it prints a letter again and again! Let's try to fix that.
-
Create a function is_this_digit(input_line) that checks if the string parameter is a digit. The function should return True or False
1.1. String contains only one digit if the string length is 1 and the character inside is digit character. To check last condition use <target_var>.isdigit() function (e.g., "2".isdigit() will return True) or string comparison such as "0" <= target <= "9"
-
Read the input from the user (use input())
-
Continue to repeat reading the input, until user inputs digit
-
When we finally have a digit provided as an input, then output it in the following sentence: Your digit is DDD (where DDD is replaced by the provided digit).
Hints!
- When we cannot predict how many times will we need to repeat the action - that is when we use the while statement.
- Call your function inside the while statement or save your function result each time and use that result in while statement.
The code I should complete:
def is_this_digit(input_line):
# Define your function here
pass
if __name__ == '__main__':
# Type your code here.
