Coding in Python: a comprehensive Beginners Guide to Learn the Realms of Coding in Python

The Break Keyword
If you want to exit the loop without running the code that remains, you can
add a break statement to the program. The break statement tends to redirect
the flow of a program and allow you to execute the code of your choice.
pgm = input("Please enter the name of the office item that you have
purchased:")
pgm += "\n(You have to enter 'q' to exit the program.) "
while True:
item = input(pgm)
if item == 'q':

---

break
else:
print("I have purchased the " + item.title())
= RESTART: C:/Users/saifia computers/Desktop/sample.py
Please enter the name of the office item that you have purchased:table

>>>
You have another choice as well. Instead of breaking out of the loop, you can
integrate into the block of code a continue statement that will take the code
back to the start after the condition stands tested. See the following
mathematical example.

---

num = 0
while num < 40:
num += 1
if num %4 == 0:
continue
print(num)
= RESTART: C:/Users/saifia computers/Desktop/sample.py

You can see that the continue statement returned the code after a pause at the
point Python tested the condition. The num started at 0. I kept the figure
under 40 so the loop ran until 4, checked if the current number is divisible by
4 and then executed the rest of the code because the number was not divisible
by 4. Let us try another example to clear the concept fully.
num = 4
while num < 80:
num += 3
if num %4 == 0:
continue
print(num)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
