For Loop

Using for Loop and else statement. 

For Loop using range

Syntax of range is range(begin,end, step)

# Prints out the numbers 0,1,2,3,4

Example

for x in range(5):

 print(x)

# Prints out 3,4,5 increment by 1

Example

for x in range(3, 6):

 print(x)

# Prints out 3,5,7 increment by 2.

Example

for x in range(3, 8, 2):

 print (x)

Result

Using for Loop with list.

Define fruits as list and get each element as fruit from list fruits.

Example

fruits = ['banana', 'apple',  'mango','orange']

counter=0;

for fruit in fruits:   

   counter +=1   

   print str(counter), fruit

Result

Nested for Loop – Define power of Number .

Define a for loop within a loop. If break statement is inside a nested loop (loop inside another loop), break will terminate the innermost loop.

Example

for x in xrange(1, 6):

    print ('power of %d'%x)

    for y in xrange(2, 4):

        print '%d power %d = %d' % (x, y, pow(x,y))

Result

Using for Loop and else statement. 

Loop till the condition is met and then execute else statement. The else clause 

executes when the loop completes normally. This means that the loop 

did not encounter any break. If break statement is inside a nested 

loop (loop inside another loop), break will terminate the innermost loop.

Example

for x in xrange(1,10,3):

    print x

   ß--------------- Break  # this will terminate and else will not execute.

else:

    print 'Final x = %d' % (x)

Result

Using for with string and print each letter from string.

Print each character from the string using index of string.

Example

string = "Good Morning"

print string

for x in string:

    print string.index(x),x

Result

Using break and continue in for Loop statement.

Example

for i in range(1,10):

   if i %2== 0:

        continue

   if i == 7:

        print 'break at',i

        break

   print i
