How to Fix SyntaxError invalid syntax in Python With Examples

 

The error message "SyntaxError: invalid syntax" in Python means that the interpreter has found a mistake in your code that prevents it from running. This is one of the most common errors, especially for beginners.

Here are the common causes and how to fix them:

1. Missing or Mismatched Parentheses

Incorrect Example:

print("Hello, World"

Error:

SyntaxError: unexpected EOF while parsing

Solution:
Add the missing closing parenthesis:

print("Hello, World")

2. Typo in Keywords or Function Names

Incorrect Example:

pront("Hello")

Solution:
Check the spelling:

print("Hello")

3. Unclosed or Mismatched Quotes

Incorrect Example:

name = "John

Solution:
Close the quotation mark:

name = "John"

4. Missing Colon : After if, for, while, def, etc.

Incorrect Example:

if x == 10
    print("Ten")

Solution:
Add a colon at the end of the condition:

if x == 10:
    print("Ten")

5. Inconsistent Indentation

Incorrect Example:

if x > 5:
print("Greater")

Solution:
Fix the indentation (use consistent tabs or spaces):

if x > 5:
    print("Greater")

6. Using Python 2 Syntax in Python 3

Incorrect Example (Python 2 style):

print "Hello"

Solution:
Use parentheses in Python 3:

print("Hello")

7. Assignment in Condition (Before Python 3.8)

Incorrect Example:

if x = 5:
    print("Five")

Solution:
Use == for comparison:

if x == 5:
    print("Five")

General Tips to Fix It:

• Carefully read the line where the error appears.
• Use a code editor like VS Code or PyCharm that highlights syntax errors.
• Run your code in parts to isolate the issue.
• Use online tools like https://www.pythontutor.com/ to visualize code execution.
