Output of print() with multiple arguments

What is the output of this Python code?

Python

print('Hello', 'World', 2024)

A Hello, World, 2024

B 'Hello' 'World' 2024

C Hello World 2024

D HelloWorld2024

💡 Hint

Remember that print() separates multiple arguments with spaces by default.

The print() function prints each argument separated by a space by default, so the output is 'Hello World 2024'.

Using print() with sep parameter

What will this code print?

Python

print('A', 'B', 'C', sep='-')

A A-B-C

B A B C

C ABC

D A, B, C

💡 Hint

The sep parameter changes the separator between printed items.

The sep='-' tells print() to put a dash between each argument instead of the default space.

Effect of end parameter in print()

What is the output of this code?

Python

print('Line1', end='***')
print('Line2')

A Line1***Line2

B Line1 Line2

C

Line1
Line2

D Line1***\nLine2

💡 Hint

The end parameter replaces the default newline after print.

By default, print ends with a newline. Here, end='***' replaces it, so the next print continues on the same line after ***.

Understanding print() with flush parameter

What does the flush=True parameter do in the print() function?

A It delays the output until the program ends.

B It changes the separator between printed items.

C It adds a newline after the printed text.

D It forces the output to be written immediately to the screen or file.

💡 Hint

Think about when output appears on the screen.

flush=True forces Python to write the output immediately, useful when output is buffered and you want to see it right away.

Output of print() with complex expressions

What is the output of this code?

Python

print(f"Sum: {sum([i for i in range(3)])}", end='; ')
print('Done')

A Sum: 6; Done

B Sum: 3; Done

C

Sum: 3
Done

D

Sum: 6
Done

💡 Hint

Calculate the sum of numbers from 0 to 2 and watch the end parameter.

range(3) is 0,1,2; sum is 3. The end='; ' keeps the cursor on the same line with a semicolon and space before printing 'Done'.
