I want to read a csv file into a data frame from a certain folder with pandas. This folder contains several csv files. They contain different information.
df = pd.read_csv(r'C:\User\Username\Desktop\Statistic\12345678_Reference.csv')
The first part in the filename (1 - 8 is variable). I want to read it in the file which ends with '_Reference.csv', but I have no clue how to manage it. I googled, but could not find a solution if there are more than one csv file in the same folder.
CodePudding user response:
If you import os
, then you can use functions for for navigating the file system.
os.listdir(path)
will return a list of all of the file names in a directory.
[f for f in os.listdir(path) if f.endswith("Reference.csv")]
Will return a list of all files names ending with "Reference.csv". In your scenario, it sounds like there will be only one item in the list.
So, [f for f in os.listdir(path) if f.endswith("Reference.csv")][0]
would return the filename that you're looking for.
Then you can construct a path using the filename, and feed it to pd.read_csv().
