PCEP Using `sep=` and `end=` in `print()` 2

Question 1

What is the output of `print('a', 'b', 'c', sep='-')`?

Accepted Answer

a-b-c

Answer

The `sep='-'` argument places a hyphen between each argument passed to print.

Question 2

What does `print('Hello', end='')` do differently than `print('Hello')`?

Accepted Answer

Suppresses the trailing newline

Answer

By default `end='
'`, so passing `end=''` removes the newline that would follow the output.

Question 3

What is printed by:
```
print(1, 2, 3, sep=', ', end='!')
```

Accepted Answer

1, 2, 3!

Answer

`sep=', '` joins the numbers with comma-space, and `end='!'` replaces the newline with `!`.

Question 4

Which call produces the output `Hello World` (no newline at the end)?

Accepted Answer

Both A and C

Answer

Both `print('Hello World', end='')` and `print('Hello', 'World', end='')` suppress the newline (the latter also uses default `sep=' '`).

Question 5

What is the output of:
```
for i in range(3):
    print(i, end=' ')
```

Accepted Answer

0 1 2

Answer

Each iteration prints the number followed by a space instead of a newline, resulting in `0 1 2 ` with a trailing space.
