The document discusses Python's break and continue statements and how they can alter the normal flow of a loop. It provides examples of using break to terminate a loop entirely, and continue to skip the remaining code in the current iteration and move to the next one. It also discusses printing patterns using nested for loops, with the outer loop representing rows and the inner representing columns. The user is prompted to input the number of rows, then nested for loops print the pattern by iterating the number and columns on each line.

score=int(input("Enter the score"))
if score>90 : grade ="A“
elif score>80 : grade="B“
elif score >70: grade="C“
elif score>60 : grade="D“
elif score>50:grade="E“
else : score = "F“
print ('nGrade for',score,'is : ',grade)
Output
Enter the score 85
Grade for 85 is : B

In Python, break and continue statements can alter the flow of a
normal loop
The continue statement is used to skip the rest of the code inside a loop
for the current iteration only. Loop does not terminate but continues on
with the next iteration
• Loops iterate over a block of code until the test expression is false
• but sometimes we wish to terminate the current iteration
• or even the whole loop without checking test expression.
The break statement terminates the loop containing it. Control of the
program flows to the statement immediately after the body of the
loop.

# Use of break statement inside the loop
for val in "string":
if val == "i":
break
print(val)
print("The end")
Output
s
t
r
The end

There is a typical structure to print any pattern: Outer loop
represents rows and the inner loop represents
Accept the number of rows from a user using input() function or
decide the size of a pattern.
Iterate the number of rows using outer for loop and range() function
Next, the inner loop or nested for loop to handle the number of
columns. Inner loop iteration depends on the values of the outer
loop.
Print start, number, asterisk, Pyramid, and diamond pattern using the
print() function.
Add a new line after each row, i.e. after each iteration of outer for
loop so you can display pattern appropriately.

rows = 6
for num in range(rows):
for i in range(num):
print(num, end=" ") # print number
# line after each row to display pattern correctly
print(" ")
1
2 2
3 3 3
4 4 4 4
5 5 5 5 5

12. Python programming
Try to print different patterns using python

13. Thankyou

14. Python programming
Then program should accept
n numbers
Write a python program to accept n
Rewrite using for loop and
Upload Program on

Then print the largest and second largest of
n numbers
