The python print() function as the name suggests is used to print a python object(s) in Python as standard output.
Syntax: print(object(s), sep, end, file, flush)
Parameters:
- Object(s): It can be any python object(s) like string, list, tuple, etc. But before printing all objects get converted into strings.
- sep: It is an optional parameter used to define the separation among different objects to be printed. By default an empty string(“”) is used as a separator.
- end: It is an optional parameter used to set the string that is to be printed at the end. The default value for this is set as line feed(“\n”).
- file: It is an optional parameter used when writing on or over a file. By default,, it is set to produce standard output as part of sys.stdout.
- flush: It is an optional boolean parameter to set either a flushed or buffered output. If set True, it takes flushed else it takes buffered. By default, it is set to False.
Example 1: Printing python objects
Python3
# sample python objects list = [ 1 , 2 , 3 ] tuple = ( "A" , "B" ) string = "GeeksforLazyroar" # printing the objects print ( list , tuple ,string) |
Output:
[1, 2, 3] ('A', 'B') GeeksforLazyroar
Example 2: Printing objects with a separator
Python3
# sample python objects list = [ 1 , 2 , 3 ] tuple = ( "A" , "B" ) string = "GeeksforLazyroar" # printing the objects print ( list , tuple ,string, sep = "<<..>>" ) |
Output:
[1, 2, 3]<<..>>('A', 'B')<<..>>GeeksforLazyroar
Example 3: Specifying the string to be printed at the end
Python3
# sample python objects list = [ 1 , 2 , 3 ] tuple = ( "A" , "B" ) string = "GeeksforLazyroar" # printing the objects print ( list , tuple ,string, end = "<<..>>" ) |
Output:
[1, 2, 3] ('A', 'B') GeeksforLazyroar<<..>>
Example 4: Printing and Reading contents of an external file
For this, we will also be using the Python open() function and then print its contents. We already have the following text file saved in our system with the name neveropen.txt.
To read and print this content we will use the below code:
Python3
# open and read the file my_file = open ( "neveropen.txt" , "r" ) # print the contents of the file print (my_file.read()) |
Output:
Example 5: Printing to sys.stderr
Python3
# Python code for printing to stderr # importing the package # for sys.stderr import sys # variables Company = "GeeksforLazyroar.org" Location = "Noida" Email = "contact@geeksforgeeks.org" # print to stderr print (Company, Location, Email, file = sys.stderr) |
Output:
GeeksofrLazyroar.org Noida contact@geeksforgeeks.org
