Python print() function

Lesson#9

Python print function is used to print something (text or values of variables) on screen.

x = 10
print("x: ", x)

# prints x: 10 on screen

Values of multiple variables can be printed with single print statement:

x = 10
y = 5
z = x + y
print("x: ", x, " y: ", y , " z: ", z)

# output
# x:  10  y:  5  z:  15

Formatted print()

Formatted print is another option available with print statement in which variables can be referred directly in single string:

The above example can be re-written using formatted print() with which the code look much cleaner as below:

x = 10
y = 5
z = x + y
print(f"x: {x} y: {y} z: {z}")

# output
# x:  10  y:  5  z:  15

Note the difference between x and {x}. x means x as string and {x} means value of variable x. So x prints x and {x} prints 10 (value of x).

It may be noted that formatted print starts with f before the string argument to print function.
