Day 15: A Closer Look at Python Control Statements

Introduction :

Welcome back to my Python journey! Yesterday, I laid the foundation with control structures in python.

Today, I dove into control statements, essential building blocks of any programming language. Let's explore what I learned!

Control Statement

break

continue

pass : it is a key word.

pass is a control statment.

pass is used to define empty body in python.

pass:

• if True:

• pass

• no body

Loop Termination :

Loop can terminated in two different ways:

1. Normal: if the loop is terminates with the head condition false

2. AbNormal : if the loop is terminated with the head condition true. (using break)

Example :

for i in range (1, 10) :

if i == 8 :

break

print (i)

print ("out of loop")

Example :

for i in range (1, 10) :

if i == 6 :

i+=2

continue

print (i)

example:

from time import sleep

i = 1

while i <= 10 :

j =1

if i == 3 :

break

while j <= 5 :

if j == 3 :

break

print ("i am inner while loop")

j += 1

print ("i am while loop")

i +=1

print ("outside of while loop")

Example:

#print multiplication table from 1 to 8

from time import sleep

number = 1

while number <= 10:

if number > 8:

break

i=1

while i <=10:

print (i * number,end = ' ')

i += 1

number += 1

print ('\n')

sleep(1)

Example:

#print multiplication table from 1 to 10 but not print 5 table

from time import sleep

number = 1

while number <= 10:

if number==5:

number +=1

continue

if number > 8:

break

i=1

while i <=10:

print (i * number,end = ' ')

i += 1

number += 1

print ('\n')

sleep(1)

break :

• break transfer the control from body to outside of the loop and terminate the loop.

continue:

• continue control statement is used to avoid / skip the execution of loop body for a specific condition.

• continue transfer the control from body to head position

Note:

break & continue is not allowed outside loop pass is allowed at any position

Example:

#Count the number of Digits of an int number given by user in runtime

number= int(input("enter a number"))

count = 0

while number > 0 :

count +=1

number= number //10

print ("number of digit",count)

Example:

#Check a number is Palindrome or not

number= int(input("enter a number"))

temp = number

rev =0 while number > 0 :

digit = number % 10

rev = rev * 10 + digit

number //=10

if temp == rev :

print ("number is palindrome")

else:

print ("number is NOT palindrome")

Challenges :

1. Understanding loop iteration.

2. Handling errors.

Resources :

1. Official Python Documentation: Control Structures

2. W3Schools' Python Tutorial: Control structures

3. Scaler's Python Course: Control Flow

Goals for Tomorrow :

1. Explore something more on functions.

   Conclusion :

Day 15’s a success!
