 Loops in Python
Example

# While loop study in python

i = 3
while i < 10:
    print(i)
    i=i+1

# using the break statement in while loop
print(" this is the result of break statement")
i = 1
while i<10:
    print(i)
    if i == 5:
        break
    i+=1

# using the continue statement in while loop
print("this is the continue statement in while loop...continue (skip)")
i = 10
while i <30:
    i +=1
    if i == 20:
        continue
    print(i,"this is continue")
# using if else in while loops
i = 1
while i<10:
    print(i)
    i+=1
else:
    print("i is no longer than 10")


# for loop exmaple in python:
iteams = ["mango","apple","pineapple"]
for x in iteams:
    print(x)


for x in "mango":
    print(x) # printing in sequence of chracter


# using break statement in for loop
  #example 1
company = ["google","microsoft","bing"]
for x in company:
    if x=="microsoft":
        break
    print(x)
print("second example below of break")
 #example 2

brand = ["bmw","tata","mahindra","audi"]
for x in brand:
    print(x)
    if x=="mahindra":
        break

# using else in for loop

for x in range(8):
    print(x)
else:
    print("finally finishing the code")

# nested for loop
company = ["mangal","himgange","navratan","patanjali"]
product = ["dalmot","hair oil","powder & oil","many iteams"]
for x in company:
    for y in product:

        print(x,y)

# using pass statement
 # example 1
y= range(5)
for y in x:
    pass
 # example 2
for x in [1,2,3,4,5,6,7,8]:
    pass
