I have a bunch of csv files, I am reading them using pandas from python. I want to use a combination of map & lambda functions to do this.

I have tried this,

NN=pd.read_csv(filename[0].split('\n')[0])
map((lambda x: NN.append(pd.read_csv(x.split('\n')[0]))), filename)

the map function does not append to NN.

Thanks for your help.

Have you tried using concat and a generator expression instead:

NN = pd.concat((pd.read_csv(f.split('\n')[0]) for f in filename))
