# Exercise:

# range 10, even num  square, odd num double with while loop

i=1

while i<10:

    i =i+1

    if i%2==0:

        print(i**2)

    else:

        print(i*2)

 

#output       

4

6

16

10

36

14

64

18

100

 

# Now same exercise,but we wanna see whatz goin on inside loop, So

i=1

while i<10:

    i =i+1

    if i%2==0:

        print(i,'%2','remainder =',i%2,'so',i,'is Even num-->sqr',i,'**2','=',i**2)

    else:

        print(i,'%2','remainder =',i%2,'so',i,'is Odd num-->dble',i,'*2','=',i*2)

 

# Note: if i=0 à1 %2 remainder = 1 so 1 is Odd num-->dble 1 *2 = 2

#output

2 %2 remainder = 0 so 2 is Even num-->sqr 2 **2 = 4

3 %2 remainder = 1 so 3 is Odd num-->dble 3 *2 = 6

4 %2 remainder = 0 so 4 is Even num-->sqr 4 **2 = 16

5 %2 remainder = 1 so 5 is Odd num-->dble 5 *2 = 10

6 %2 remainder = 0 so 6 is Even num-->sqr 6 **2 = 36

7 %2 remainder = 1 so 7 is Odd num-->dble 7 *2 = 14

8 %2 remainder = 0 so 8 is Even num-->sqr 8 **2 = 64

9 %2 remainder = 1 so 9 is Odd num-->dble 9 *2 = 18

10 %2 remainder = 0 so 10 is Even num-->sqr 10 **2 = 100

break example

# print only Python, Java

for i in ('Python','Java','Swift',"C",'C++'):

if i== 'Swift':

                                break

                print(i) 

output

Python

Java

(1)    break example

while True: # to keep condition True forever to avoid freq run

    num = int(input('Guess your number: '))

    if num ==15:

        print('You won, Number was:',num)

        print("'break'loop acted")

        break

    # while loop will continue printing whatever input was and ask again to Enter Guess yr num.

# when input =15,

# output à You won, Number was 15 \n ‘break’ loop acted

 

 

(2)    break example with while loop

i = 1

while i < 10:

                print(i)

                i = i+1

                if i == 5:

                                break

 

#output              

0

1

2

3

4

# Notice ‘break’ loop acted and 5 is NOT printed.

 

 

(3)    break example with while loop

while i < 10:

                print(i)

                i = i+1

                if i == 5:

                            print (‘break’ loop acted and so 5 is NOT printed.)

                                break

 

#output              

0

1

2

3

4

‘break’ loop acted and so 5 is NOT printed.

 

(4)    break example with for loop

 

s = 'Anybody can learn Python coding only must practice daily '

for i in s:

                print(i,end='')

                if i=='m':

                                break

# output

Anybody can learn Python coding only m

(10)    age = int(input("Enter yr age "))
