#### LOOPS #####

### While Loop

Having below 3 parts

1) #Initialisation / Assign the value

2) #Condition

3) #Increment/Decrement

i=1 #Initialisation

while i<=5: #Condition

print("Raja",i)

i=i+1 #Increment/Decrement

## reverse while loop

i=10

while i>=1:

print("Mango",i)

i=i-1

-----

i=1

while i<=5:

print(i)

i=i+1

i=1

while i<=20:

print(i)

i=i+1

## nested while loop

i=1

while i<=5:

print(i, "Raja", end="")

j=1

while(j<=3):

print("Gopal", end="")

j=j+1

i=i+1

print()

#Example

i=1

while i<=5:

print(i,"Raja : ", end="")

j=1

while j<=5:

print(j,"Monkey, ",end="")

j=j+1

i=i+1

print()

#Example

##3 NAME RAJAGOPALNAIDU with while loop ###

#### For loop ########

##String

#to retrive above string results in a single line

## For loop with "List":

##LIST

l=["Raja", 99, 99, 8.7] # this list is having str,int,flot

for i in l:

print(i)

## For loop with "Tuple":

##Tuple

t=(1,2,2,3,4,6,7,8)

for i in t:

print(i)

T=(11)

for i in range(T):

print(i)

print(i)

for i in range(1, 50, 5): # Here 1 is starting value, 50-1 is ending value & 5 is itreation (difference) which means every 5th number will be in results

print (i)

#reverse

for i in range(11,0,-2):

print(i)

## which we don't want to print the values are Divisible by 5

for i in range(1,50):

if i%5!=0:

print(i) # if you observe this results 5 divisible numbers will not display means 5,10,15,20,25........

print(i)

###### NESTED FOR LOOP#####

for i in range(1,100):

if i%3!=0:

if i%5!=0:

print(i)

### Above Same query we can write as below:

for i in range(1,50):

if i%3!=0 and i%5!=0:

print(i)

### by using or both divisable values will not display

for i in range(1,61):

if i%3!=0 or i%5!=0:

print(i) # from this out put 15,30,45,60 will be missing as these nubers will divisible by both 3, 5

for i in range(1,61):

if i%3==0 and i%5==0:

print(i) # will display 15,30,45,60 these nubers only as these will divisible by both 3, 5

for i in range(1,61):

if i%3==0 or i%5==0:

print(i) #3,5 both divisible numbers will dislay

############ Key words "break", "Continue", "Pass" ###########

# 1) Break

# 2) Continue

# 3) Pass

# 1) Break

while using wending michene if we try to enter morethen avilable items in the mechene then

# if with in range by using FOR LOOP

for i in range(5):

if i>=10:

print("Given count is out of range")

break

print(i)

# # if out of range by using FOR LOOP

for i in range(11):

if i<10:

print("Given count is out of range")

break

print(i)

### if with in range by using WHILE LOOP (with out "input" option)

#ex: wending mechene has 3 items only but upto 5 items that will give so

# if customer enter/looking for 5 items from the mechene, will give 3 items and for 4th system will diplay not avilable message

av=3 ## av = avilability

i=1

while i<=5:

if i>av:

print("Input items are not avilable in the mechene")

break

print(i)

i+=1 # 3 items will get but for 4th item will display "Input items are not avilable in the mechene" message

##### To run same queries by using same WHILE & FOR LOOPS #####

for i in range(31):

if i%3!=0: #divisible by 3 number are not displayed from the results

print(i)

for i in range(1,31):

if i%3==0: #divisible by 3 number will displayed from the results

##Same testing using while loop
