print() function prints the given object to the standard output device (screen) or to the text stream file.
message = 'Python is fun'# print the string message print(message)# Output: Python is fun
The full syntax of
print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)
- objects - object to the printed. * indicates that there may be more than one object
- sep - objects are separated by sep. Default value:
- end - end is printed at last
- file - must be an object with write(string) method. If omitted,
sys.stdoutwill be used which prints objects on the screen.
- flush - If True, the stream is forcibly flushed. Default value:
Note: sep, end, file, and flush are keyword arguments. If you want to use sep argument, you have to use:
print(*objects, sep = 'separator')
print() Return Value
It doesn't return any value; returns None.
Example 1: How print() works in Python?
print("Python is fun.") a = 5 # Two objects are passedprint("a =", a)b = a # Three objects are passedprint('a =', a, '= b')
Python is fun. a = 5 a = 5 = b
In the above program, only the objects parameter is passed to
print() function (in all three print statements).
' 'separator is used. Notice the space between two objects in the output.
- end parameter
'\n'(newline character) is used. Notice, each print statement displays the output in the new line.
- file is
sys.stdout. The output is printed on the screen.
- flush is
False. The stream is not forcibly flushed.
Example 2: print() with separator and end parameters
a = 5print("a =", a, sep='00000', end='\n\n\n')print("a =", a, sep='0', end='')
a =000005 a =05
We passed the sep and end parameters in the above program.
Example 3: print() with file parameter
In Python, you can print objects to the file by specifying the file parameter.
Recommended Reading: Python File I/O
sourceFile = open('python.txt', 'w') print('Pretty cool, huh!', file = sourceFile) sourceFile.close()
This program tries to open the python.txt in writing mode. If this file doesn't exist, python.txt file is created and opened in writing mode.
Here, we have passed sourceFile file object to the file parameter. The string object 'Pretty cool, huh!' is printed to the python.txt file (check it in your system).
Finally, the file is closed using the
