Question

I have a list that looks like this separate=[['I','wnet','to','the','mal,'],['and','bouht','a','new','shirt.'],['What','did','you','do','todya?']]

I'm going to run this through a program which will identify the misspelled words and replace them with the correct word but the list of words in the Webster Dictionary that I am using only uses lowercase letters- can I temporarily change all of the letters to lowercase but then in the end return the original upper and lower case words?

I know about str.upper() and str.lower() and set.capitalize

It seems like I want to use something like str.capwords() but inversely... I want to split the list into words(already done) and then make capital letters lower case.

Explanation / Answer

from numpy import ndarray

separate=[['I','wnet','to','the','mal,'],['and','bouht','a','new','shirt.'],['What','did','you','do','todya?']]

separatenew=ndarray((len(separate),),list)

for i in range(len(separate)):

a=[]

for j in separate[i]:

a.append(j.lower())

separatenew[i]=a

print separatenew

for i in range(len(separate)):

for j in range(len(separate[i])):

separatenew[i][j]=separate[i][j]

print separatenew
