How to get individual digits from a number?
===========================================
by modulo division of number and floor division of number with 10, we can get individual digits

-> then continue to find the sum of digits of a number.

For Loop:
=========

range()
=======
-> an operator
	which can be used to generate numbers from the specified range
Syntax:
	range(start)
	range(start, stop)
	range(start, stop, step)

a = range(10)
# range() can generate values from '0' default
# until start - 1
print(a)

b = range(10,20)
print(b)

c = range(1,100,15) # generate numbers from 1 to 99 with difference of 15
print(c)

for a in range(10):
    print(a)
print()

for b in range(10,20):
    print(b)
print()
for c in range(1,100,15):
    print(c)

String Concatenation:
=====================
Joining of one string at the end of first string is called as "String concatenation".
-> represented with an operator ==> '+'
Syntax:
	String1 + string2
