Input() function in Python is not working [duplicate]

Question

I'm new to Python, and I'm trying to compile a VERY simple code in Python (using Atom editor), and after I run this code:

name = input("Name:")
print(f"hello, {name}")

And after typing in any name (in this case I simply typed in n, I get this error message:

Name:n

Traceback (most recent call last):
  File "hello_name.py", line 1, in <module>
    name = input("Name:")
  File "<string>", line 1, in <module>
NameError: name 'n' is not defined

I hope you can help! Thanks!

Answer 1

You need to use raw_input instead of input, because input runs eval on the input. (Only in python 2, in Python 3 input has the same behavior of raw_input and raw_input is removed)

What that means is that after getting your input, python would evaluate your input as if it was code.
Try entering "3+2*5-2" in the input and see the output.

(Note that writing something like:"x = 5" won't work, because eval just evaluates an expression, like y+3 (assuming y is defined) and it does not actually run the code)

(But really, you should use python 3 if you are just learning Python and you are not already used to python2)

Answer 2

yes its right i also phase a problem like that and my code is

name = input("enter you name: ")
print(name)

so i enter my name Anshu then it show this error

Traceback (most recent call last): File "/home/anshu/Projects/coding/python/dictnory_problem.py", line 6, in search = input("enter your keyword: ") File "", line 1, in NameError: name 'anshu' is not defined

then i change my code i use

name = raw-input("enter your name")
print(name)
