Creating folders from csv in python

I am trying to create a number of folders from a csv file and then run a python script inside each. The following code is to create the folders. It runs but doesn't create anything!

import errno    
import os
import csv
import pandas as pd

mountains_column_name = "mountains"

#read from the csv of mountains

data = pd.read_csv('1500mountains.csv', encoding='utf8')

#column called mountains has the names:
if mountains_column_name not in data.columns:
    raise ValueError("Missing Mountain column in input data")

mountains = data[mountains_column_name].tolist()


def mkdir_p(mountains):
    try:
        os.makedirs('\vince\Desktop\WhatMountainThat\dataset')
    except OSError as exc:  # Python >2.5
        if exc.errno == errno.EEXIST and         
os.path.isdir('\vince\Desktop\WhatMountainThat\dataset'):
            pass
        else:
            raise
 mkdir_p(mountains)

I'd forgotten to call mkdir! When I call it now I get the following :

TypeError: mkdir_p() missing 1 required positional argument: 'mountains'

Lets assume that your_list_from_csv vaiable is list of dirs you want to create. Then create floders like so:

import os

path = "/your/path"
your_list_from_csv = ["dir1", "dir2"]

for new_dir in your_list_from_csv:
    dir_path = "{0:s}/{1:s}".format(path, new_dir)
    try:
        os.mkdir(dir_path)
    except FileExistsError as err:
        print("Folder Exists")

output:

$ ls -la
total 16
drwxrwxr-x 4 rszamszur rszamszur 4096 Nov  1 13:06 .
drwxrwxr-x 7 rszamszur rszamszur 4096 Nov  1 13:06 ..
drwxrwxr-x 2 rszamszur rszamszur 4096 Nov  1 13:06 dir1
drwxrwxr-x 2 rszamszur rszamszur 4096 Nov  1 13:06 dir2

Edit

For Windows users out there you will need to provide path with disk partition while using backslashes instead. Example:

path = "c:\your\path"
