Python Loops - While Loop

 With the while loop we can execute a set of statements as long as a condition is true.

while expression:
    statement(s)

Example: A program that adds number up to num where num is entered by the user.          The total = 1+2+3+4… up to the supplied number.

Program: Generate the following sequences using while loop:
Even Numbers Between 50 and 75
Numbers between 1 and 100 in reverse order that are divisible by 5

#A) Even Numbers Between 50 and 75
a=50
print("Even Numbers Between 50 and 75 is")
while(a<=75):
    if (a%2==0):
        print(a,end=' ')
    a+=1

Output:

Even Numbers Between 50 and 75 is
50 52 54 56 58 60 62 64 66 68 70 72 74 

#B) Numbers between 1 and 100 in reverse order that are divisible by 5
i=100
print("Numbers between 1 and 100 in Reverse Order that are divisible by 5:") 
while (i>=1):
  if (i%5==0):
    print (i, end = '  ')
  i = i - 5

Output:

Numbers between 1 and 100 in Reverse Order that are divisible by 5:
100  95  90  85  80  75  70  65  60  55  50  45  40  35  30  25  20  15  10  5
