distance = getDistanceByPoint(principalDf, kmeans) # number of observations that equate to the 13% of the entire data set number_of_outliers = int(outliers_fraction*len(distance)) # Take the minimum of the largest 13% of the distances as the threshold threshold = distance.nlargest(number_of...
36. Write a Python program to find the largest palindrome made from the product of two 4-digit numbers. According Wikipedia - A palindromic number or numeral palindrome is a number that remains the same when its digits are reversed. Like 16461, for example, it is "symmetrical". The term...
Ruff can be used as a drop-in replacement for Flake8 when used (1) without or with a small number of plugins, (2) alongside Black, and (3) on Python 3 code. Under those conditions, Ruff implements every rule in Flake8. Ruff also re-implements some of the most popular Flake8 plugin...

Remember that the[0-9]+is “greedy” and it tries to make as large a string of digits as possible before extracting those digits. This “greedy” behavior is why we get all five digits for each number. The regular expression module expands in both directions until it encounters a non-dig...
Sometimes, you need to determine the number of characters in a string. In this situation, you can use the built-in len() function: Python >>> len("Pythonista") 10 When you call len() with a string as an argument, you get the number of characters in the string at hand. Another...
