Python Error: Name 'd' Not Defined

In your Python code, you encountered an error message stating that "name 'd' is not defined." This error typically occurs when you attempt to access or modify a variable without initializing or defining it beforehand.

In the code snippet you provided, you request user input for a name and a description. The error is triggered when you input "d" instead of a string, such as your actual name.

In Python 2.x, the input() function interprets the input as a Python expression and expects a variable. When you enter "d," Python attempts to find a defined variable named d, but it does not exist.

To resolve this issue, you can either use raw_input() in Python 2.x, which returns a string without evaluating it, or switch to Python 3.x, where input() handles string input correctly.

Solution:

In Python 2.x:

Name = raw_input('What is your Name? ')
Desc = raw_input('Describe yourself: ')
Copy after login

In Python 3.x:

Name = input('What is your Name? ')
Desc = input('Describe yourself: ')
Copy after login
