Common Mistakes

Forgetting the quotes around __main__

Using __main__ without quotes

Comparing to "main" instead of "__main__"

The special variable __name__ equals the string "__main__" when the script is run directly.

2fill in blank

medium

Common Mistakes

Calling greet() without the if condition

Using __main__ without quotes

Comparing to "main" instead of "__main__"

The function greet() should be called only if __name__ equals "__main__".

3fill in blank

hard

Fix the error in the code to print the module name when imported.

Python

print("Module name is", [1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Printing the string "__name__" instead of the variable

Using __main__ variable which is undefined

Putting quotes around __name__

The variable __name__ holds the module name or "__main__" if run directly.

4fill in blank

hard

Fill both blanks to create a script that prints differently when run or imported.

Python

def main():
    print("Running as main script")

if [1] == [2]:
    main()
else:
    print("Imported as a module")

Drag options to blanks, or click blank then click option'

A__name__

B"__main__"

C__main__

D"__name__"

💡 Hint

Common Mistakes

Using __main__ without quotes

Swapping the order of variable and string

Using "__name__" as string instead of variable

The condition checks if __name__ equals the string "__main__" to run main().

5fill in blank

hard

Fill all three blanks to create a script that defines a function and runs it only when executed directly.

Python

def [1]():
    print("Function called")

if [2] == [3]:
    [1]()

Drag options to blanks, or click blank then click option'
