Printing a number in python is very easy and you can do it in two ways.
To print the number as it is.
eg: print(10)
To print it using a variable
eg: num = 79
print(num)
Various arithematic operations can be performed in python like +,-,* and /.
eg: print(78+22)
print(78+22.934)
In a similar fashion you can also use the '%' operator to find remainder of division.
eg: print(20%3)
Concatenation is python is only possible if the input is a string, For a number to be concatenated it should be first converted to a string or ',' operator should be used.
eg: print('10, is a number)
