从url python下载文本文件

我正在使用Python2.7开发web应用程序。我正在尝试从特定URL下载文本文件并保存在应用程序的静态文件夹中。以下是我的代码：

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'


def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'static/forcast.txt'
    fx = open(des_url,"w")
    for line in lines:
        fx.write(line+ "\n")
    fx.close()

download(uurl)

现在，我运行此操作并得到以下错误：

Traceback (most recent call last):
  File "/Users/sanam/PycharmProjects/ff/ff.py", line 17, in <module>
    download(uurl)
  File "/Users/sanam/PycharmProjects/ff/ff.py", line 12, in download
    fx = open(des_url,"w")
IOError: [Errno 2] No such file or directory: '/static/forcast.txt'

回溯（最近一次呼叫最后一次）：
文件“/Users/sanam/PycharmProjects/ff/ff.py”，第17行，在
下载（uurl）
文件“/Users/sanam/PycharmProjects/ff/ff.py”，第12行，下载中
fx=打开（des_url，“w”）
IOError:[Errno 2]没有这样的文件或目录：'/static/forcast.txt'

代码没有问题，因为它将文件下载到python脚本的同一目录中。因此，请指定文件夹的位置

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'

def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'folder/forcast.csv'
    fx = open(des_url,"w")
    for line in lines:
        fx.write(line+ "\n")
    fx.close()

download(uurl)

这很有效。使用

os.getcwd（）

查找将此文件写入哪个目录。/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7/Users/sanam/PycharmProjects/ff/ff.py回溯（最后一次调用）：文件“/Users/sanam/PycharmProjects/ff/ff.py”，第17行，在下载（uurl）文件“/Users/sanam/PycharmProjects/ff/ff.py”中，第12行，在下载fx=open（des_url，“w”）IOError:[Errno 2]中没有这样的文件或目录：'/static/forcast.txt'您创建了文件夹吗？您必须首先创建文件夹。您创建了

/Users/sanam/PycharmProjects/ff/static

？@sanamasghar Stael有一个正确的想法，就是让

os.getcwd（）+'/static/forcast.txt'

将其放置在

/Users/sanam/PycharmProjects/ff/static

中没有这样的文件或目录：'/Applications/PyCharm 2.app/Contents/bin/static/forcast.txt'

from urllib2 import urlopen

uurl = 'http://textfiles.com/100/ad.txt'

def download(t_url):
    response = urlopen(t_url)
    data = response.read()
    txt_str = str(data)
    lines = txt_str.split("\\n")
    des_url = 'folder/add.txt'
    with open(des_url,"w"):
        for line in lines:
            fx.write(line+ "\n")


download(uurl)
