programs using loops

0_Session5.py

'''
using for loop to print numbers 1 to 10
range(a, b+1) starts from a and ends at b
'''

for i in range(1, 11):
    print(i)

1_for_loop_range.py

'''
using for loop to print a range of numbers
'''

start = int(input("Beginning range: "))
end = int(input("Ending range: "))
for number in range(start, end+1):
    print(number)

2_step_counting.py

'''
print the numbers in a given range while incrementing by 4
The range() takes a third argument, step that increments the number by that value after every iteration
'''

start = int(input("Beginning range: "))
end = int(input("Ending range: "))
for number in range(start, end+1, 4):
    print(number)

3_print_even.py

'''
print all the even numbers in the given range of numbers
'''

start = int(input("Beginning range: "))
end = int(input("Ending range: "))
for number in range(start, end+1):
    if number % 2 == 0:
        print(number)

4_sum_of_numbers.py

'''
print the sum of first n numbers
'''

n = int(input("Enter n: "))
sum = 0
for number in range(1, n+1):
    sum = sum + number

5_print_in_reverse.py

'''
print the numbers from 10 to 1.
step counting of -1 is used to reduce the value by 1 for every iteration
'''
for i in range(10, 0, -1):
    print(i)

6_multiplication_table_while.py

'''
print the multiplication table of any given number - using while
'''
number = int(input("Enter any number to get it's table"))
i = 1
while i <= 10:
    print(i,"*",number,"=", i*number)
    i = i + 1

7_multiplication_table_for.py

'''
print the multiplication table of any given number - using for loop
'''
number = int(input("Enter any number to get it's table"))
for i in range(1, 11):
    print(i,"*",number,"=", i * number)
    i = i + 1
