For Loop in Python

Introduction

 

In this article, I will explain the for loop in Python. For loops are used for sequential traversal. For example: traversing a listing or string or array etc. In Python, there may be no C style. For a loop example: for (i=0; i<n; i + +) there is a” for in” loop, which is just like a for each loop in other languages. Let's discover ways to use a for-in loop for sequential traversals. A for statement is executing within the inside statement once or more. Once False, the next code will be executed.

 

Syntaxfor i in range condition:
       statement

Example

 

Here's a simple program for the "for loop”.

for i in range(1,15):
    print(i)

Output 

 

Remember that i's value is 15, so the block of code will be executed 15 times.

 

 

For Loop and Break statement

 

With the break declaration, we can stop the loop even if the while condition is true.

 

Syntax

for i in range condition:
   if condition:
   break

Example

 

Here's a simple program for the "for loop” and “break statement”

for i in range(1,15):
  if i == 6:
    break
  print(i)

Output

 

Note that it runs up until the number 6, and after the number, there's no display in the Output screen.

 

 

For Loop and Continue Statement

 

The continue statement is used to leave a sum statement, then it continues with the next statement.

 

Syntaxfor i in range condition:
   if condition:
   continue

Example

 

Here's a simple program for the "for loop” and “condition statement”.

for i in range(1,15):
  if i == 6:
    continue
  print(i)

Output

 

Note that the number 6 is missing in the output.

 

 

For Loop and Pass Statement

 

The pass statement is used to write an empty loop statement. Pass is also used for empty control statements.

 

Syntax

for i in range condition:
   if condition:
   pass

Example

 

Here's a simple program for the “for loop” and “pass statement”.

for i in range(1,15):
  if i == 6:
    pass
  print(i)

Output

 

Pass statements do not change anything.

 

 

For Loop and Else Statement

 

In the else statement, we will run a block of code once while the condition is false.

 

Syntaxfor i in range condition:
   statement
else:
   statement

Example

 

Simple program for ”for loop “and “else statements”.

for i in range(1,10):
  print(i)
else:
  print ("hello c#")

Output 

 

Remember, i's value is 10, so the block of code will be executed 10 times. Then the else code will be executed one time.
