废话不多说,直接上代码,取得当前目录:

path = os.path.dirname(sys.argv[0])

遍历当前目录:

def traveldir(root_dir):
    for dir_or_file in os.listdir(root_dir):
        path = os.path.join(root_dir, dir_or_file)
        print path
        if os.path.isdir(path):
            traveldir(path)

csv文件读写:

import csv
csv_data = csv.reader(open("filename.csv"))
for line in csv_data:
    print line
