input() error - NameError: name '…' is not defined

0 votes

I am getting an error when I try to run this simple script:

input_variable = input ("Enter your name: ")
print ("your name is" + input_variable)

Let's say I type in "dude", the error I am getting is:

line 1, in <module>
input_variable = input ("Enter your name: ")
File "<string>", line 1, in <module>
NameError: name 'dude' is not defined

Hello @kartik,

  • You should use raw_input if you are using python-2.7. 
  • When you use input() on a variable (for example: s = input('Name: ')), it will execute the command ON the Python environment without saving what you wrote on the variable (s) and create an error if what you wrote is not defined.

raw_input() will save correctly what you wrote on the variable (for example: f = raw_input('Name : ')), and it will not execute it in the Python environment without creating any possible error:

input_variable = raw_input('Enter Your Name : ')
print("Your Name Is  : " + (input_variable))

Hope this is useful!!
Thank You!!
