Python print() Function

Write values to standard output (or a file), separated by spaces and followed by a newline. Both are configurable.

Syntax

print(*objects, sep=" ", end="\n", file=None, flush=False)

Parameter	Description
`*objects` optional	Any number of values; each is converted with `str()`.
`sep` optional	Text between values. Default: `" "`
`end` optional	Text after the last value. Default: `"\n"`
`file` optional	Where to write: `sys.stdout` by default, or any object with `write()`.
`flush` optional	Flush the output immediately. Default: `False`

None.

Separators and line endingsTry it yourself

print("Hello", "world", 2026)
print("a", "b", "c", sep="-")
print("no newline", end=" | ")
print("next")

Output

Hello world 2026
a-b-c
no newline | next

Printing formatted valuesTry it yourself

name, score = "Ada", 95.456
print(f"{name} scored {score:.1f}")
print("Total:", 3 + 4)

Output

Ada scored 95.5
Total: 7

Errors and unpacking a listTry it yourself

import sys
print("something went wrong", file=sys.stderr)
rows = [["id", "name"], [1, "Ada"]]
for row in rows:
    print(*row, sep="\t")

Output

something went wrong
id	name
1	Ada

print(*items) prints a list's items separated by spaces instead of the list itself.
Use flush=True for progress messages that must appear immediately.

Version	Change
Python 3.0	Added
Python 3.3	Added the `flush` parameter.

input() · Read a line of text typed by the user, after printing an optional prompt. The result is always a string.
format() · Format a single value with a format spec, such as format(3.14159, '.2f') giving '3.14'. The same mini-language as f-strings.
repr() · Return the developer-friendly string representation of an object, often valid Python code that recreates the value.
str() · Convert a value to its readable text form, or decode bytes into a string. Strings are immutable sequences of characters.
