Python 2 7 getting user input and manipulating as string without quotations

Question

I want to get a string from a user  and then to manipulate it   testVar   input  Ask user for something      Is there a way for testVar to be a string without me having the user type his response in quotes   i e   Hello  vs  Hello  If the user types in Hello  I get the following error   NameError  name  Hello  is not defined

If you want to use input instead of raw input in python 2 x then this trick will come handy      if hasattr   builtins     raw input          input raw input   After which   testVar   input  Ask user for something      will work just fine

The function input will also evaluate the data it just read as python code  which is not really what you want   The generic approach would be to treat the user input  from sys stdin  like any other file  Try  import sys sys stdin readline     If you want to keep it short  you can use raw input which is the same as input but omits the evaluation

Use raw input   instead of input     testVar   raw input  Ask user for something      input   actually evaluates the input as Python code   I suggest to never use it   raw input   returns the verbatim string entered by the user

This is my work around to fail safe in case if i will need to move to python 3 in future   def  input msg     return raw input msg

We can use the raw input   function in Python 2 and the input   function in Python 3  By default the input function takes an input in string format  For other data type you have to cast the user input   In Python 2 we use the raw input   function  It waits for the user to type some input and press return and we need to store the value in a variable by casting as our desire data type  Be careful when using type casting  x   raw input  Enter a number      String input  x   int raw input  Enter a number       integer input  x   float raw input  Enter a float number       float input  x   eval raw input  Enter a float number       eval input   In Python 3 we use the input   function which returns a user input value   x   input  Enter a number      String input   If you enter a string  int  float  eval it will take as string input  x   int input  Enter a number       integer input   If you enter a string for int cast ValueError  invalid literal for int   with base 10   x   float input  Enter a float number       float input   If you enter a string for float cast ValueError  could not convert string to float  x   eval input  Enter a float number       eval input   If you enter a string for eval cast NameError  name     is not defined  Those error also applicable for Python 2
