Pandas is the important package for data analysis in Python. There are different versions available for Pandas. Due to some version mismatch, it may create some problems. So we need to find the version numbers of the Pandas. We can see them easily using the following code.We can use the command like below, to get the version −pandas.__version__Example>>> import pandas as pd >>> print(pd.__version__) 0.25.2 >>>We can also get the version of the dependencies using the function like below −pandas.show_versions() >>> pd.show_versions() INSTALLED VERSIONS ------------------ commit : None python : 3.7.1.final.0 python-bits : 64 OS : Windows OS-release : 7 ...

An anagram is a rearrangement of the characters of a word or a phrase to generate a new word, using all the original characters exactly once. For example, thing and night are anagrams of each other. An anagram substring search includes two strings (text, pattern); we need to search the given text for any substring that contains the same characters as the pattern, in any order. Scenario Following is an example scenario: Input: str1="cbaebabacd", str2="abc" Output: [0, 6] Explanation: In this case, The substring "cba" at index 0 is an anagram of "abc". The substring "bac" at index 6 is an ... Read More

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, using all the original letters exactly once. For example, thing and night are anagrams of each other. In this article, we are going to learn how to check an anagram in a Python program using collections.Counter() method. This method counts the number of occurrences of each element in a collection (like characters in a string), helping us to compare two words for identical character counts. For example, Scenario Input: str1= "listen", str2= "silent" Output: True Two strings are said ... Read More
