Without if statements?
Apologies typing on my phone
def input_checker(input_str):
You are comparing the content of strings, not their truth value. A string is true if it’s not empty and false if it is. The string “True” is no closer to the bool True than the string “Oranges” is.
What you are looking for is input validation. Check the content of what they wrote and respond accordingly.
why is my input being seen as a string in the firsr place if i typecasted the variable as a boolean? how do i make the input itself a bool (rather than the variable?)
Worth remembering that python uses the concepts of truthy and falsey. Empty string ("") is falsey. Any other string ("true", "false", "0", etc.) Is truthy. All bool(str) does is evaluate whether str is truthy or falsey. It does not evaluate what str actually is.
So bool(input("Input True or False ") will return False is the user input is empty and True otherwise.
