Simple Python Tutorial for printing formatted output #print() #modulo() #fstring #string смотреть онлайн

Simple python example and short video to illustrate the use of print() display formatted message on the console. It shows 4 different methods of using the print() to display output. The difference between using comma (,) and using string concatenation. It also shows how to use modulo (%) to display string in required number of decimal places. There is also an example to use fstring method to display.The examples used are very simple so that it is easy for beginner to understand.

The 4 methods discussed has the following syntax
print( " ... , varInt , ... , varFloat , ... " )
print( " ... + str(varInt) + ... + str(varFloat) + ... " )
print( " ... %d ... %.2f ... " % (var1,var2) )
print( f" ... {varInt} ... {varFloat:.2f} ... " )

The below are the codes used
############
name = "Mary"
age = 18
height = 1.777

print(name + " is " + str(age) + " years old and "+ str(height) +" m tall" )
print(name , "is" , age , "years old and", height ,"m tall" ) #add space between
print("%s is %d years old and %.2f m tall" % (name,age,height) )
print(f"{name} is {age} years old and {height:.2f} m tall")
############

Beginner may get confused with the comma and string concatenation method.
To print with a mixture of numerical (int and float) variables and string variables, we need to use str() for the string concatenation (+) method.

Note that the string concatenation (+), Modulo (%) and fstring method are just few ways to format a string.
You can also use them in input() as well to display a string on the screen to prompt user for input.
