for: iterate a clause over  the items of any sequence. The sequence can be a set of numbers or strings.

Example-1

words=['cat', 'mice', 'rabbit']

for w in words:

   print('Hello,  '+w)

---

outPut:

Hello,  cat

Hello,  mice

Hello,  rabbit

Example-2

for i in range(5):

   print(i)

---

outPut:

0

1

2

3

4

NB1: range(a,b,c)--a-start point, b-end point, c-increment. The given end point is never part of the generated sequence

Example

range(2,10,2)--->2,4,6,8

range(-20,-100,-10)-->-20,-30,-40,-50,-60,-70,-80,-90

NB2: break and continue can also be used in for statements.

Example

for i in range(-20,-100,-10):

   if i==-50:

       break

   print(i)

---

outPut

-20

-30

-40

Example: if i is larger than -50, go back to the for loop, otherwise, print the number of i

for i in range(-20,-100,-10):

   if i>-50:

       continue

   print(i)

---

outPut

-50

-60

-70

-80

-90
