Python For Loop

What is FOR LOOP?

In computer programming, a loop is a sequence of instructions that is continuously repeated until a certain condition is reached. Typically, a certain process is done. In python FOR loop is used to iterate over a sequence data type like list, tuple, dictionary, set and string until last item.

for x in "LOOPBREAK":
	print(x)

van = ["suv", "nano", "bolero"]
for item in van:
	print(item)

Python Statement

break

pass

continue

Python For Loop Syntax

for item in object:
  LOOP Body

for value in sequence:
    LOOP Body

Python For Loop Break Statement

van = ["suv", "nano", "bolero", "Bus"]

for x in van:
	if x == "Bus":
		break
	print(x)

Python For Loop Pass Statement

#Pass Statement

van = ["suv", "nano", "bolero", "Bus"]
for x in van:
	pass

Python For Loop Continue Statement

van = ["suv", "nano", "bolero", "Bus"]
for x in van:
	if x == "nano":
		continue
	print(x)

Python For Loop With Range

# Range Function Syntax
range function
range(stop)
range(start, stop, step)

with one argument

for x in range(11):
	print(x)

with two arguments

for x in range(1, 11):
	print(x)

3 arguments

for x in range(2, 21, 2):
	print(x)
for x in range(3, 31, 3):
 	print(x)

Python For Loop With Else

Python For Loop With Else Syntax

for item in object:
    LOOP Body
else:
	ELSE Body

for value in sequence:
    LOOP Body
else:
	ELSE Body

for loop with else

for x in "LOOP":
	print(x)
else:
	print("Finally loop breaked")

my_fruit_basket = ["Mango", "Orange", "Banana"]
for fruit in my_fruit_basket:
	print(fruit)
else:
	print("Basket is empty now")

Python Nested For Loop

Python Nested For Loop Syntax

for items in object:
	for item in items:
    	LOOP Body
else:
	ELSE Body

for values in sequence:
	for value in values:
		LOOP Body
else:
	ELSE Body

Nested For Loop

van = ["Maruti", "nano", "Suzuki"]
for x in van:
	print(x)
	for y in x:
		print(y)
else:
	print("Loop stopped")

for x in "LOOP":
	print(x)
	for y in x:
		print(y)
else:
	print("Loop stopped")

for x in ["Maruti", "nano", "Suzuki"]:
	print(x)
	for y in x:
		print(y)
else:
	print("Loop stopped")
