Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. Loops in Python can be created withfororwhilestatements. Python for statement Py...

Loop through sequences: used for iterating over lists, strings, tuples, dictionaries, etc., and perform various operations on it, based on the conditions specified by the user. Example: Calculate the average of list of numbers numbers = [10, 20, 30, 40, 50] # definite iteration # run...
PythonTips Don't use a for loop like this for multiple Lists in Python: a=[1,2,3]b=["one","two","three"]# ❌ Don'tforiinrange(len(a)):print(a[i],b[i]) Instead use the handyzip()function: # ✅ Doforval1,val2inzip(a,b):print(val1,val2) ...
In the code chunk above, you have two loops with around 10000 iterations. Both look the same at first sight, until you look behind the scenes and understand how these two loops work. Hint: the timeit() function gives you a clue of what might be the difference! Remember: all Python code...

In the example given below, We have two list containing the name of countries and name of capital respectively. Here, we will read the value from the two lists and construct the dictionary out of this lists. python l1=['India','Australia','Nepal','Bhutan'] l2=['Delhi','Canberra','Ka...
Python’s map() can be your ally in these situations. The following sections will walk you through some examples of how to use map() to transform iterables of string objects.Using the Methods of strA quite common approach to string manipulation is to use some of the methods of the class...
For example, if we have two lists with same length and we want to loop through them simultaneously, we use the zip function. See the example below. This function aggregates elements from two iterables and returns an iterator of tuples, where the ith tuple element contains the ith element ...
