来看文件处理Python怎么写？

文件处理

处理csv文件

如下为csv文件内容

用户名,密码,重复密码,邮箱,错误提示信息testuser1,123456,654321,hello@123.com,两次密码输入不一致。

使用python自带csv库进行处理

importcsv

importos

datafile=os.path.join('/Users/zack/Desktop/2018-08-25/zuoye','data.csv')

# print(datafile)

defread_csv():

csvdata=[]

withopen(datafile,encoding="utf-8")asf:

print("f=",f)

csvreadrer=csv.reader(f)

print("csvreader==",csvreadrer)

next(csvreadrer)

forrowincsvreadrer:

csvdata.append(row)

returncsvdata

通过csv文件中定义的内容进行解析处理

fromseleniumimportwebdriver

fromselenium.webdriver.common.byimportBy

fromparse_csvimportread_csv

rf=read_csv()

defregister(username,passwd,repasswd,email,tip_message):

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get("http://118.31.19.120:3000/signup")

driver.find_element(By.ID,"loginname").send_keys(username)

driver.find_element(By.ID,"pass").send_keys(passwd)

driver.find_element(By.ID,'re_pass').send_keys(repasswd)

driver.find_element(By.ID,'email').send_keys(email)

driver.find_element(By.CSS_SELECTOR,".span-primary").click()

# get Tip message Textresult_text=driver.find_element(By.TAG_NAME,'strong').textprint(result_text)

defrun():

forrowinrf:

register(row[],row[1],row[2],row[3],row[4])

defmain():

run()

if__name__=='__main__':

main()

日志处理

python自带日志记录模块，参考如下链接

https://docs.python.org/3/howto/logging-cookbook.html

https://docs.python.org/3/library/logging.html

定位文件get_logging.py

importlogging

deff_w():

# create logger with 'spam_application'logger=logging.getLogger('CNode_club')

logger.setLevel(logging.DEBUG)

# create file handler which logs even debug messagesfh=logging.FileHandler('spam.log')

fh.setLevel(logging.DEBUG)

# create console handler with a higher log level# ch = logging.StreamHandler()# ch.setLevel(logging.ERROR)# create formatter and add it to the handlersformatter=logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

fh.setFormatter(formatter)

# ch.setFormatter(formatter)# add the handlers to the loggerlogger.addHandler(fh)

# logger.addHandler(ch)returnlogger

将日志功能记录到登陆操作中

register.py

fromseleniumimportwebdriver

fromselenium.webdriver.common.byimportBy

fromparse_csvimportread_csv

log=f_w()

defregister(username,passwd,repasswd,email,tip_message):

driver=webdriver.Chrome()

driver.maximize_window()

driver.implicitly_wait(30)

driver.get("http://118.31.19.120:3000/signup")

driver.find_element(By.ID,"loginname").send_keys(username)

log.info('输入用户名：'+username)

# write_logging({'level':'DEBUG', 'action': '输入文本', 'name1': username})driver.find_element(By.ID,"pass").send_keys(passwd)

driver.find_element(By.ID,'re_pass').send_keys(repasswd)

driver.find_element(By.ID,'email').send_keys(email)

driver.find_element(By.CSS_SELECTOR,".span-primary").click()

# get Tip message Textresult_text=driver.find_element(By.TAG_NAME,'strong').textprint(result_text)

defrun():
