creating a folder and checking for its existence using python

Create a directory and then look to see if it has been created

create_folder("11", "course files", "GQM-test-20160623c")
check_for_folder("11", "course files", "GQM-test-20160623c")

These calls use the functions defined below:

 
def create_folder(course_id,  parent_folder_path, folder_name):
    url = baseUrl + '%s/folders' %(course_id)
    print url

    payload = {'parent_folder_path': parent_folder_path, 'name': folder_name}
    print payload

    write_to_log(course_id + "/" + parent_folder_path + "/"  + folder_name)

    r = requests.post(url, headers = header, data = payload)
    write_to_log(r.text)    

def check_for_folder(course_id,  parent_folder_path, folder_name):
    url = baseUrl + '%s/folders' %(course_id)
    write_to_log("folders of " + course_id)
    payload = {}
    r = requests.get(url, headers = header, data = payload)
    write_to_log(r.text)    

    folders_response=r.json()

    full_name_to_match='%s/%s' % (parent_folder_path, folder_name)
    print "full_name" + "\t" + "id" + "\t" + "matching: "+ full_name_to_match
    for f in folders_response:
        if (f["full_name"]  ==  full_name_to_match):
            print f["full_name"] + "\t" + str(f["id"]) + "\ttrue"
        else:
            print f["full_name"] + "\t" + str(f["id"])

Before:

./create-directory-check-it-exits.py

# will output (assuming that the folder does not already exist):

After:

Unless you specify otherwise, if you run the same program again you will get a new directory with the name: "GQM-test-20160623c 2"
Running it yet again there will a version "3", etc.
