It take values from string, list, dictionary.

s = 0
for i in range (11, 21, 2)
s=s+i
print (s)

s = 0
For i in range (2,11,2)
s=s+i
print (s)

Program to calculate the sum of numbers 1 to 100
Program:
n= 100
sum=0
for counter in ranget (1, n + 1):
sum = sum + counter
print("Sum of 1 until %d: %d" % (n,sum))
Output:
Sum of 1 until 100: 5050

?1? - i
?2? - 10

Output:
1, 3, 5, 7
End of the loop

Syntax:
for counter_variable in sequence:
statements-block 1
[else: # optional block
statement-block 2]

(i) print can have end, sep as parameters. end parameter can be used when we need to give any escape sequences like '\t' for tab, '\n' for new line and so on.
(ii) sep as parameter can be used to specify any special characters like, (comma) (semicolon) as separator between values

Python provides two types of looping constructs:
(i) while loop
(ii) for loop

a = int (input("Enter any number :"))
x="even" if a%2==0 else "odd"
print (a, "is",x)
Output 1:
Enter any number  3
3 is odd
Output 2:
Enter any number: 22 
22 is even

Syntax:
variable = variablel if condition else variable 2

Output:
Enter any number: 56
56 is an even number
Output 2:
Enter any number: 67
67 is an odd number

There may be situations in our real life programming where we need to skip a segment or set of statements and execute another segment based on the test of a condition. This is called alternative or branching.
