need some help in the following code as it goes into infinite loop and does not validate user input: the get_offset is the function. Just edited need some help with the encryption part to be done in a function defined

def get_offset(offset):while True:value = (offset)if value < 1:print("")if value > 94:print("")return offsetmy_details = display_details()get_choice = get_menu_choice()print(my_details)
print(get_choice)count = 10while count > 0:count -=1encrypted = ""choice = int(input("What would you like to do [1,2,3,4,5]: "))while choice <1 and choice > 5:print("Invalid choice, please enter either 1, 2, 3, 4 or 5.")if choice == 1:string_input = input("Please enter string to encrypt: ")input_offset = get_offset(int(input("Please enter offset value (1 to 94): ")))**for letter in string_input:x = ord(letter)encrypted += chr(x + input_offset)if x < 32:x += 94if x > 126:x -= 94print(encrypted)**

you have to assign choice new value inside inner while loop. this way, new input is considered before iterating again and again.

this should do the trick:

while choice < 1 and choice > 5:choice = int(input("Invalid choice, please enter either 1, 2, 3, 4 or 5."))

A random advice: If you want to keep dataset strictly equal to [1,2,3,4,5], you should avoid choice<1 and choice>5. This makes your program vulnerable to invalid inputs such as 3.5.

Instead, you should do this:

valid_inputs = [1, 2, 3, 4, 5]choice = int(input("Pick a number from [1, 2, 3, 4, 5]:"))while choice not in valid_inputs:choice = int(input("Invalid choice, please enter either 1, 2, 3, 4 or 5."))<rest of stuff here>

What I understood from your comments is that, in get_offset(), you want user to type a value between 1 and 94. If user enters something out of that range, you want to ask question again and again. The code below should do what you want:

def get_offset():# first, ask for a value.offset = int(input("Enter a value between 1 and 94:"))while offset < 1 and offset > 94:# if the value is invalid, trap user inside this while loop.# user will be stuck here (while loop will return true) # until a valid input is received.offset = int(input("Invalid input. Please enter a value between 1 and 94:"))# if we proceed down here, it means we are over while loop # and it implies that user has given us valid input. return value.return offset

Secondly, inside main while loop, you can call get_offset() like this:

if choice == 1:string_input = input("Please enter string to encrypt: ")input_offset = get_offset()
