2. Loop in python :-
n=0
print("this is a program to find sum of first 100 numbers")
for i in range(5):
i=i+1
n=n+i
print('the sum is ' + str(n))
4.Example program:-
print('what is your name?')
name=input()
print('hello ' + name)
x=len(name)
print('number of characters in your name is:' + str(len(name)))

5. Example 4

num1 = input('Enter first number: ')
num2 = input('Enter second number: ')
# Add two numbers
sum = float(num1) + float(num2)
# Display the sum
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))
