str.translate gives TypeError - Translate takes one argument (2 given), worked in Python 2

Question

I have the following code

import nltk, os, json, csv, string, cPickle
from scipy.stats import scoreatpercentile

lmtzr = nltk.stem.wordnet.WordNetLemmatizer         


        

Answer 1

This is how translate works:

yourstring.translate(str.maketrans(fromstr, tostr, deletestr))

Replace the characters in fromstr with the character in the same position in tostr and delete all characters that are in deletestr. The fromstr and tostr can be empty strings and the deletestr parameter can be omitted.

example:

str="preetideepak12345aeiou"
>>> str.translate(str.maketrans('abcde','12345','p'))

output:

'r55ti4551k1234515iou'

here:

a is translated to 1
b is translated to 2
c is translated to 3 and so on
and p is deleted from string.
