Python SyntaxError: f-string: expecting '}'

This exception "SyntaxError: f-string: expecting '}'" occurs when we using formatted string, and the variable or expression in the formatted string is not ended with the closing curly brace }.

Let us recreate this exception by using a formatted string, and not ending the variable with closing curly brace.

Python Program

# Given variable
name = "Apple"

# Formatted string
result = f"Hello {name!"

# Print resulting string
print(result)

Output

  File "/Users/pythonexamples_org/workspace/main.py", line 5
    result = f"Hello {name!"
                            ^
SyntaxError: f-string: expecting '}'

Solution

The solution is straight forward. We have to enclose the variable or expression in curly braces. Place the ending curly brace, and the exception is gone.

Python Program

# Given variable
name = "Apple"

# Formatted string
result = f"Hello {name}!"

# Print resulting string
print(result)

Output

Hello Apple!

That's it! This is how we resolve the Python exception "SyntaxError: f-string: expecting '}'".

Summary

In this tutorial, we solved the exception "SyntaxError: f-string: expecting '}'" by writing the trailing curly brace after the variable or expression used in the formatted string.
