how to write add frequency in particular file by reading a csv file and then making a new file of multiple csv file by adding frequency

A problem (possibly the problem) is the lines which use the get function: count = frequency.get(word,0) Since the dictionary is empty at the start of the loop, the get function is passing a value of 0 to count and count1. The subsequent updates to the dictionary are applying a value of zero As a

Any chance you could post one line of data so we can see what we have to work with? Also - have you taken a look at Jake VanderPlas's notebooks? There's lot of help with pandas to be found there: https://github.com/jakevdp/PythonDataScienceHandbook Paul. On 24 June 2017 at 10:32, Bhaskar Dhariya
