用户在 python 输入中输入点时出错

Question

im wondering why is

  File "<string>", line 1
    .
    ^
SyntaxError: unexpected EOF while parsing

coming when i execute following script and including dot in input.

answer = input('enter 1: ')
if answer == 1:
    print('nice')
else:
    print('please enter "1"')
    return

I have been wondering this pretty long, and now im trying to ask here if someone could help me. So i can't include dots or anything else that basic letters and numbers my input. I thought there could be easy way to find this thing out. There is other code i need to fix below, with same error.

email = str(input('required* Your mail: '))
print('your mail is : ' + email)

now, it needs to include dot and at mark.

Answer 1

The code here seems ok, except for the fact you're using return without a function.

And the code wouldn't work when I put I type 1, because you need to cast the var "aswer".

The code should be like this:

answer = int(input('enter 1: '))
if answer == 1:
    print('nice')
else:
    print('please enter "1"')

Answer 2

You are putting a string and you are checking if is this a number , that is your error, so if you want to ask every time if the answer is wrong you could do this:

while True:
    answer = input('enter 1: ')
    if answer == "1":
        print('nice')
        break
    else:
        print('please enter "1"')
