Ok the title is a bit weird. But, basically what i want to ask is:

read = input("Enter some numbers: ")
# The user should only enter numbers and nothing else

But the thing is the user can enter something else other than a numerical value. How do i stop someone from entering an alphabet in realtime from the terminal?

Lets say the user inputs 123 then enters an "e". How do i make this e not even appear on the terminal even if the user presses the e key?

CodePudding user response：

you can repeat asking int values if user enters a string.

while True:
    try:
        #
