In Python 2, print is a statement:
print "Hello World"
print # print a newline
print "No newline", # add trailing comma to remove newline
print >>sys.stderr, "Error" # print to stderr
print("hello") # print "hello", since ("hello") == "hello"
print() # print an empty tuple "()"
print 1, 2, 3 # print space-separated arguments: "1 2 3"
print(1, 2, 3) # print tuple "(1, 2, 3)"
In Python 3, print() is a function, with keyword arguments for common uses:
print "Hello World" # SyntaxError
print("Hello World")
print() # print a newline (must use parentheses)
print("No newline", end="") # end specifies what to append (defaults to newline)
print("Error", file=sys.stderr) # file specifies the output buffer
print("Comma", "separated", "output", sep=",") # sep specifies the separator
print("A", "B", "C", sep="") # null string for sep: prints as ABC
print("Flush this", flush=True) # flush the output buffer, added in Python 3.3
print(1, 2, 3) # print space-separated arguments: "1 2 3"
print((1, 2, 3)) # print tuple "(1, 2, 3)"
The print function has the following parameters:
print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)
sep is what separates the objects you pass to print. For example:
print('foo', 'bar', sep='~') # out: foo~bar
print('foo', 'bar', sep='.') # out: foo.bar
end is what the end of the print statement is followed by. For example:
print('foo', 'bar', end='!') # out: foo bar!
Printing again following a non-newline ending print statement will print to the same line:
print('foo', end='~')
print('bar')
# out: foo~bar
Note : For future compatibility, print function is also available in Python 2.6 onwards; however it cannot be used unless parsing of the print statement is disabled with
from __future__ import print_function
This function has exactly same format as Python 3’s, except that it lacks the flush parameter.
See PEP 3105 for rationale.
