    • In the context of most data science work, Python for loops are used to loop through an iterable object (like a list, tuple, set, etc.) and perform the same action for each entry. For example, a for loop would allow us to iterate through a list, performing the same action on each item in the list.
      • Python supports to have an else statement associated with a loop statement. If the else statement is used with a for loop, the else statement is executed when the loop has exhausted iterating the list. If the else statement is used with a while loop, the else statement is executed when the condition becomes false.
      • You might have noticed that methods like insert, remove or sort that only modify the list have no return value printed - they return the default None. 1 This is a design principle for all mutable data structures in Python.. Another thing you might notice is that not all data can be sorted or compared. For instance, [None, 'hello', 10] doesn't sort because integers can't be compared to ...
      • Is there a way to just add multiple items to a dictionary or do you have to make the value a list ? I have initialised it as a list now but it is adding items more than once to the list. and also adding items that should be in key1 and key2. Does Python iterate a list item against every if statement.
      • Iterator in Python is simply an object that can be iterated upon. An object which will return data, one element at a time. Technically speaking, Python iterator object must implement two special methods, __iter__() and __next__(), collectively called the iterator protocol. An object is called iterable if we can get an iterator from it.
      • Rationale. One of the most common uses of for-loops in Python is to iterate over an interval of integers. Python provides functions range() and xrange() to generate lists and iterators for such intervals, which work best for the most frequent case: half-open intervals increasing from zero. However, the range() syntax is more awkward for open or closed intervals, and lacks symmetry when ...
      • Python Program to return Elements in a List Example 2. This python program is the same as above. But this time, we are using For Loop to iterate every element in a list, and printing that element. This approach is very useful to alter the individual item using this Python index position.
      • List - Traversing List elements using Loops Loops are used to carry out an operation over and over again for a given number of times. As List can have any number of items hence it is very important to have some mechanism to pick each element of any list one by one and perform an operation on it.
