python将文件写成csv文件保存到本地

举个例子:

import csv
import os

path='/tmp/'
file='test.csv'
def generate_csv(path,file):
    if not os.path.exists(path):
        os.mkdir(path)
    files=os.path.join(path,file)
    # os.system('touch %s' %files)
    with open(files,'w') as f:
        writer=csv.writer(f)
        writer.writerow(['client_name','os..','path'])
    return files

def main():
    generate_csv(path,file)

if __name__=='__main__':
    main()
