Runtime Error

What This Error Means

This error occurs when a variable or function is used before it has been declared or initialized. In this case, the variable 'user_input' is being used in a print statement but has not been assigned a value.

Why It Happens

This error typically happens when a programmer tries to use a variable or function before it has been declared or initialized, often due to a misunderstanding of the order of operations in a program.

How to Fix It

1. 1To fix this error, you need to assign a value to the 'user_input' variable before using it. You can do this by using an input function to get user input, for example:
2. 2// Before (broken code)
3. 3print(user_input)
4. 4// After (fixed code)
5. 5user_input = input('Enter your name: ')
6. 6print(user_input)

Example Code Solution

print(user_input)

user_input = input('Enter your name: ')
print(user_input)
