print() parameters and formatting in Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the sep parameter in the print() function?

The sep parameter defines the string inserted between multiple values printed. By default, it is a space (' ').

beginner

How does the end parameter affect the print() output?

The end parameter sets what is printed at the end of the output. By default, it is a newline (\n), so the next print starts on a new line.

What does the file parameter do in print()?

The file parameter specifies where the output goes. By default, it prints to the screen (standard output), but you can redirect it to a file or other stream.

beginner

How can you format a number to show two decimal places using print()?

Use an f-string with format specifier like f"{number:.2f}". This rounds and shows the number with two decimals.

beginner

What is the difference between print('Hello', end='!') and print('Hello')?

The first prints Hello! without moving to a new line after. The second prints Hello and moves to the next line.

What is the default separator between values in print()?

A A space

B A comma

C No separator

D A newline

By default, print() inserts a space between multiple values.

Which print() parameter changes what is printed at the end?

A sep

B flush

C file

D end

The end parameter sets the string printed after the output, defaulting to a newline.

How do you print multiple values without spaces between them?

A Use <code>end=''</code>

B Use <code>sep=' '</code>

C Use <code>sep=''</code>

D Use <code>file=''</code>

Setting sep='' removes spaces between printed values.

What does print(f"{value:.2f}") do?

A Prints value as integer

B Prints value with 2 decimal places

C Prints value in scientific notation

D Prints value as string

The format specifier .2f rounds and prints the number with two decimals.

How can you print output to a file instead of the screen?

A Use <code>print(..., file=open('file.txt', 'w'))</code>

B Use <code>print(..., file=filename)</code> where filename is a string

C Use <code>print(..., sep='file.txt')</code>

D Use <code>print(..., end='file.txt')</code>

You must open the file and pass the file object to the file parameter.

Explain how the sep and end parameters change the behavior of the print() function.

Think about what appears between and after printed items.

Describe how to format a floating-point number to two decimal places when printing in Python.
