WordCount

Task:Count the number of words in a file.

Python

1 data=pd.read_csv(file,sep="\n",header=None)
2 tmp=[]
3 data=data.iloc[:,0].apply(lambda x:tmp.extend(x.split()))
4 pd.Series(1,tmp).groupby(level=0).count()

It's just to split the contents by empty characters. It will be very troublesome to remove other punctuations that do not have statistical meanings.

esProc

    A  
1   =lower(file("T.txt").read()).words().groups(~:word;count(1):count)  

esProc provides the word() function to split the string into words, and a one-liner can complete the task.
