FREE PCEP Using `sep=` and `end=` in `print()` Questions and Answers

Question 1

What is the output of the following code?

```python
print('apple', 'banana', 'cherry', sep=',')
```

Accepted Answer

apple,banana,cherry

Answer

The `sep` keyword argument specifies the separator to be used between the arguments of the `print()` function. By default, it's a space, but here it has been set to a comma, so the items are printed with commas between them.

Question 2

What is the output of this code snippet?

```python
print('Hello', end=' ')
print('World!')
```

Accepted Answer

Hello World!

Answer

The `end` keyword argument specifies what to print at the end of the line. By default, it's a newline character (`
`). Here, it's set to a space for the first `print` call, so the second `print` call will start on the same line, immediately after the space.

Question 3

Which line of code will produce the output: `1-2-3`?

Accepted Answer

print(1, 2, 3, sep='-')

Answer

To place a hyphen between the arguments, you must specify `sep='-'`. The other options either use the default space separator, use the hyphen for the `end` argument, or result in a syntax error.

Question 4

What is the output of the following code?

```python
for i in range(3):
    print(i, end='')
```

Accepted Answer

012

Answer

The loop iterates for `i` values 0, 1, and 2. In each iteration, the `print` function is called with `end=''` which means no character (not even a space or newline) is printed at the end. This causes all the numbers to be printed consecutively on the same line.

Question 5

What are the default values for the `sep` and `end` arguments in the `print()` function?

Accepted Answer

sep=' ' and end='
'

Answer

By default, the `print()` function separates its arguments with a single space (`' '`) and ends its output with a newline character (`'
'`), which moves the cursor to the next line for subsequent output.
