In this article, we will learn about various types of list methods available to us in Python 3.x. Or earlier. These operators allow us to perform the basic operations on the list content.In & Not in operators“in” operator  − This operator is used to check whether an element is present ... Read More

In this article, we will learn about iteration/traversal of a dictionary in Python 3.x. Or earlier.A dictionary is an unordered sequence of key-value pairs. Indices can be of any immutable type and are called keys. This is also specified within curly braces.Method 1 − Using iterables directlyExampledict_inp = {'t':'u', 't':'o', ... Read More

In this article, we will learn about iterating/traversing over a list in Python 3.x. Or earlier.A list is an ordered sequence of elements. It is a non-scalar data structure and mutable in nature. A list can contain distinct data types in contrast to arrays storing elements belonging to the same ... Read More

In this article, we will learn about iterating/traversing over a set in Python 3.x. Or Earlier.It is an unordered collection of objects without any duplicates. This can be done by enclosing all the elements within curly braces. We can also form sets by using type casting via a keyword “set”.Method ... Read More

In this article, we will learn about iterating/ traversing over characters of a string in Python 3.x. Or earlier.The string is a collection of characters which may contain spaces, alphabets or integers. They can be accessed using indexes or via references . Some commonly implemented methods are shown below.Method 1 ... Read More

We have usually seen the print command in python printing one line of output. But if we have multiple lines to print, then in this approach multiple print commands need to be written. This can be avoided by using another technique involving the three single quotes as seen below.Example Live Demoprint(''' ... Read More

A contingency table is a table showing the distribution of one variable in rows and another variable in columns. It is used to study the correlation between the two variables. It is a multiway table which describes a dataset in which each observation belongs to one category for each of ... Read More

Lists can be added in python resulting in creation of a new list containing elements from both the lists. There are various approaches to add two lists and they are described below. But in all these cases the lists must be of same length.Using Append()Using append() we can add the ... Read More

In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given pos form we need to convert it into its equivalent sop formThe conversion can be done by first counting the number of alphabets in the pos form and then calculating all ...
