python import all files in directory

1# Basic syntax:
2import glob # Package for Unix-style pathname pattern expansion
3import os   # Python operating system interface
4
5directory = '/path/to/directory/with/files/'
6# Obtain list of filenames that end in .txt in the directory
7all_files = glob.glob(os.path.join(directory, "*.txt"))
8# Where os.path.join creates the os-specific path to each file

10# Import data however you like. To append data in a single pandas 
11# dataframe and a single list, you can do:
12your_list = [ ]
13for filename in all_files:
14    dataframe = pd.read_csv(filename, index_col=None, header=0, sep="\t")
15    your_list.append(dataframe)
