Basic Python module error

Question

So I'm learning python, from a java background, for my new job, and I've run into the following error.

I tried running this module on the terminal (using mac), then through IDLE. All futile.

 userName = input("What is your name?: ")
 lengthName = str(len(usernName))
 yourName = "\nYour name is " + userName + " and is " + legnthName + " letters long."
 print(yourName)
 input("\nPress enter to exit")

When this is executed in the terminal and I type for the first input : "John" I get this as a result:

 File "[...]", line 1, in <module>
 userName = input("What is your name?: ")
 File "<string>", line 1, in <module>
 NameError: name 'John' is not defined

Similarly, when executed via IDLE:

 Traceback (most recent call last):
 File "/Users/zachmartin/Desktop/python fails/lol.py", line 2, in <module>
 lengthName = str(len(usernName))
 NameError: name 'usernName' is not defined

What's going on here?

Answer 1

Two problems:

• You should be using raw_input() rather than input() (because input() will treat what you type as Python code and try to evaluate it).

• You have a typo, userName vs. usernName (note the extra n). (Also legnthName later on.)
