We offen use loop statements for repeating statements. One of that statement is for loop.
Here is the syntax of for loop:
1 2 3 4 5 6 | for <variable> in <sequence>: <statements> else: <statements> |
Offen use:
1 2 3 4 | for i in range(start,finish <,step>): print(i) |
Simple example:
1 2 3 4 5 6 7 | fruits = ["banana", "orange","strawberry","lemon"] for fruit in fruits: print("Great, delicious " + fruit) else: print("finally fruits is over :)") |
Python “For Loop” Examples
Example 1: Program to list numbers that are fully divisible from 1 to 100 by 3 or 5
1 2 3 4 5 | for i in range(1,101): if i%3==0 or i%5==0: print(i) |
Example 2: Program to list 100 from the number entered by the user
1 2 3 4 5 6 7 8 | #www.python-examples.com firstNumber =int(input("Enter a number under 100. Input start number:")); for i in range(firstNumber,100): print(i) |
Example 3: Program the sum of the numbers between two numbers according to the specified step
1 2 3 4 5 6 7 8 9 10 | #www.python-examples.com firstNumber =int(input("Input start number:")); secondNumber=int(input("Input finish number:")); stepNumber =int(input("Input step number:")); for i in range(firstNumber,secondNumber,stepNumber): print(i) |
Example 4: Calculate exponent of a number without using math.pow method in Python
1 2 3 4 5 6 7 8 9 10 11 12 | #www.python-examples.com baseNumber =int(input("Enter base nummber:")); exponentNumber =int(input("Enter exponent number:")); result=1; for i in range(1,exponentNumber+1): result=result*baseNumber print(result) |
