Python print() function

The print() function outputs text into the terminal (screen) or another output device. The message is usually a string, but you can print other things, whatever you want to show on the screen.

Definition and usage

The print() function outputs whatever you pass as parameter.

print("Hello world")

The examples below demonstrate how you can use the print() function with Python 3. You can type them in the Python iteractive shell or run it as a .py file.

print('Welcome to learning how to use print in python3')    

print('a')

# Outcome: a
print(9)

#Printing of numbers.
# Results: 9
print([1,2,3,4,5])

#Printing of lists
# Results: [1, 2, 3, 4, 5]
print((1,2,3,4,'5'))

# Results: (1, 2, 3, 4, '5')
print({'a':1, 'b':2})

# Results: {'a': 1, 'b': 2}
print('my name is %s,age is %d' %('lucky',66))

#formatted print
# Result: my name is lucky,age is 66
print('%.3f'%(39.122221568))
