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 it,
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')
Return Value from print()
It doesn't return any value; returns None.
Example 1: How print() works in Python?
print("Python is fun.") a = 5 # Two objects are passed print("a =", a) b = a # Three objects are passed print('a =', a, '= b')
Python is fun. a = 5 a = 5 = b
In the above program, only 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 = 5 print("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 python.txt file (check it in your system).
Finally, the file is closed using
