Creating a folder with timestamp
提问by user1927396
Currently am creating files using the below code,I want to create a directory based on the timestamp at that point in the cwd,save the directory location to a variable and then create the file in the newly created directory,does anyone have ideas on how can this be done?
目前正在使用下面的代码创建文件，我想根据 cwd 中那个点的时间戳创建一个目录，将目录位置保存到一个变量，然后在新创建的目录中创建文件，有没有人知道如何可以这样做吗？
def filecreation(list, filename):
#print "list"
with open(filename, 'w') as d:
d.writelines(list)
def main():
list=['1','2']
filecreation(list,"list.txt")
if __name__ == '__main__':
main()

You mean, something like this?
你是说，像这样的事情？
import os, datetime
mydir = os.path.join(os.getcwd(), datetime.datetime.now().strftime('%Y-%m-%d_%H-%M-%S'))
os.makedirs(mydir)
with open(os.path.join(mydir, 'filename.txt'), 'w') as d:
pass # ... etc ...
Complete function
功能齐全
import errno
import os
from datetime import datetime
def filecreation(list, filename):
mydir = os.path.join(
os.getcwd(),
datetime.now().strftime('%Y-%m-%d_%H-%M-%S'))
try:
os.makedirs(mydir)
except OSError as e:
if e.errno != errno.EEXIST:
raise # This was not a "directory exist" error..
with open(os.path.join(mydir, filename), 'w') as d:
d.writelines(list)
Update:check errno.EEXISTconstant instead of hard-coding the error number
更新：检查errno.EEXIST常量而不是硬编码错误号
