What are jump statements in Python?

Key takeaways:

  • Jump statements in Python are used to modify the normal flow of a program by transferring control to another part of the code, based on specific conditions.

  • Python supports four types of jump statements: continue (skips to the next iteration), break (exits the loop), pass (a null operation), and return (terminates a function and returns a value).

  • Jump statements allow developers to handle loops and function execution more effectively, making programs more efficient and enabling better control over the flow of execution.

A jump statement alters the normal flow of a program by transferring control to a specific line of code when a particular condition is met. Simply put, it redirects the program’s execution to another statement based on a specified condition.

Types of jump statements

Four types of jump statements are supported by Python:

  • continue

  • break

  • pass

  • return

Continue statement

The code will skip every statement that comes after the continue statement inside the loop and move on to the following iterations when it comes across the continue statement.

for i in range(1,11):
     if i==5:
        continue
     print(i,end=" ")

Break Statement

The break statement terminates the loop containing it. The control of the program will come out of this loop.

for i in range(10):
    if i==4:
       break
    print(i,end=" ")

Pass statement

Pass statement in Python is a null operation used when the statement is syntactically required.

def check_number(num):
    if num < 0:
        pass  # This is a placeholder for future code
    elif num == 0:
        print("Zero")
    else:
        print("Positive number")
check_number(-5)
check_number(0)
check_number(10)

Return statement

One kind of jump statement that ends a function and gives a value back to the calling function is the return statement. Essentially, it calls a function, runs the statements inside, and returns a predetermined value.

def add(x, y):
 
    # returning the addition of x and y
    return x + y
 
# Driver Code
result = add (3, 5)
 
print(result)

Conclusion

Jump statements in Python provide control over the flow of execution by allowing programs to skip, terminate, or redirect code execution based on specific conditions. With statements like continue, break, pass, and return, developers can manage loops and functions more effectively, improving program efficiency and enabling precise flow control. These tools are essential for writing clean, optimized, and maintainable Python code.

What are the types of Jump statements supported by Python?

  • continue: Skips the remaining statements in the loop and proceeds with the next iteration.
  • break: Terminates the loop containing it and exits the loop.
  • pass: Acts as a null operation where a statement is syntactically required, but no action is needed.
  • return: Terminates a function and returns a specified value to the calling function.

What are jump statements in Python, and what is their purpose?

Jump statements in Python are used to alter the normal flow of a program by transferring control to a specific line of code when a particular condition is met. They redirect the program’s execution to another statement based on the specified condition.

What is the purpose of the return statement in Python?

One kind of jump statement is the return statement, which ends a function and gives the caller function a value. It is used to carry out the function’s statements and output a predetermined value.
