Python Program-1

(1) Develop programs to understand the control structures of python

1) While Loop,   
2) For in Loop,

3) Continue Statement,   
4) Break Statement

Program Code:
1) While Loop: 

print("Lab-1-While Loop")

# prints Hello 3 Times
count = 0
while (count < 3):   
    count = count+1
    print("Hello Python.")

Output:While Loop:

       

2) For in Loop:
# For in Loop
print("\nString Iteration")   
s = "Python"
for i in s :
    print(i)

print("List Iteration")
l = ["A", "for", "Apple"]
for i in l:
  print(i)

Output:For in Loop:


       

3) Continue Statement:  
# Prints all letters except 'e' and 's'
for letter in 'Hello Python.': 
    if letter == 'e' or letter == 's':
         continue
    print ("Current Letter :", letter )
    var = 10

Output:Continue Statement:




4) Break Statement:
for letter in 'helloworld': 
    # break the loop as soon it sees 'e' 
    # or 's'
    if letter == 'e' or letter == 's':
         break
print ("Current Letter :", letter)

Output:Break Statement:
