There are two ways to do this. First is like this: inp = raw_input() # Get the input. if inp == "": # If it is a blank line... break # ...break the loop. The second is like this: inp = raw_input() # Get the input again. Note that if you are on Python 3.x, you will need to replace raw_input with input.

Aug 24, 2012 · num = input('Enter number between 1 - 5:') if 1 <= num <= 5: print 'number is fine' . break. else: print 'number out of range' It will continue to loop until the user enters a number in the specified range. Otherwise, the added try/except code will catch non-numeric input: try: num = input('Enter number between 1 - 5:') if 1 <= num <= 5:

5 days ago · In Python, for and while loops are used to iterate over a sequence of elements or to execute a block of code repeatedly. When it comes to user input, these loops can be used to prompt the user for input and process the input based on certain conditions. In this article, we will explore how to use for and while loops for user input in Python.

Jun 13, 2021 · Try creating a while loop, and only break out of this if a condition is met. newuser = input('enter y/n') if newuser == "y": print("Hello New User") break. elif newuser == "n": print("Hello Existing User") break. else: print("Please try again") I was wondering if someone here could help better explain For loops than my textbooks.

2 days ago · To iterate over the indices of a sequence, you can combine range() and len() as follows: In most such cases, however, it is convenient to use the enumerate() function, see Looping Techniques. A strange thing happens if you just print a range: In many ways the object returned by range() behaves as if it is a list, but in fact it isn’t.

Apr 4, 2025 · Else allows us to specify a block of code that will execute if the condition (s) associated with an if or elif statement evaluates to False. Else block provides a way to handle all other cases that don't meet the specified conditions. Example: age = 10 if age <= 12: print("Travel for free.") else: print("Pay for ticket.") Travel for free.

Read all the tutorials related to the topic of Python Sets. Loops in Python. Loops allow you to execute a block of code multiple times. Python provides two main types of loops: for loops and while loops. For Loops. The for loop in Python is designed to iterate over a sequence (like a list, tuple, dictionary, set, or string):

Skips the rest of the current iteration and checks the condition again. num = 10 while num > 0: num -= 1 if num % 2 == 0: continue print(num) # Output: 9 7 5 3 1 (skips even numbers)

Jul 30, 2020 · In python, to do this, we need input() function. Let’s have a look at code. You can accept integer and float values as well. You just need to covert them from string to int or float. While loop runs a block of code when the given condition is True.

Jan 26, 2025 · What is an if loop? An if loop in Python is a control flow statement that allows you to execute a block of code only if a certain condition is met. The condition is a boolean expression that evaluates to either True or False. If the condition is True, the code block following the if statement is executed; if it's False, the code block is skipped.
