python print examples

Here are some examples you can print strings or variables in python on stdout.

Print a string with newline in the end

By default python will append a newline in the end.

print "Hello\n"
print "Hello2"
s = "Hello3"
print s

Print a string without newline

One can use sys.stdout.write to print without newline

import sys
sys.stdout.write("Hello-")
sys.stdout.write("World\n")

Hello-World

Print multiple strings with comma

Multiple strings or variables can be printed using comma and it will add space between the strings and newline after last string.
We can use sys.stdout.write to print without newline

v1 = "Hello"
print v1, "Hello2"

Concatenate and print multiple strings with plus

In case a variable is not of string type, it needs to be converted to string using str()

print "Hello" + " World"
i = 2
print "Hello" + str(i)

Hello World
Hello2

Print formatted string

Using %s will print arguments to string if needed using str(). You can also use %d to print integers. A detailed list can be seen at python site – string formatting operations.
