为什么我的 function 会出现这个 IndentationError？

Question

I was developing a function in python. However I get this error IndentationError: unindent does not match any outer indentation level

what should i do? Here is my code

def customerdetails():
      Firs_tname = input("Enter your First name:")
      Last_name = input("Enter your last name:")
      Age = input("Age:")
      Address =input("Enter your address:")
      Postcode = input("Enter your Postcode:")
      Email = input("Email:")
      Phone = int(input("Phone Number:"))
    customerdetails()

I will use this function again and again

Answer 1

customerdetails() is inside the same function it's trying to call. You cannot call a function from inside itself this way. For this code to work customerdetails() must not be indented. Here is the correct code:

def customerdetails():
      Firs_tname = input("Enter your First name:")
      Last_name = input("Enter your last name:")
      Age = input("Age:")
      Address =input("Enter your address:")
      Postcode = input("Enter your Postcode:")
      Email = input("Email:")
      Phone = int(input("Phone Number:"))
customerdetails()

Also, for indenting you should use tabs, as they are much more consistent than spaces (not everyone knows 4 spaces is the correct indentation), especially in an established text editor like VSC. Some people prefer spaces, but personally I feel they just make things unnecessarily difficult.
