程序化更新所有pip

为了自己安装的pip组件，写了个一揽子更新全部pip，自己写了个（代码中的路径自行修改），感觉用着还可以，代码如下：

# -*- coding: utf-8 -*-

import os

tempfile1 = 'd:/a.txt'

tempfile2 = 'D:/pipupdata.bat'

python_path = '"D:/Program Files/python/python.exe"'

pip_path = '"D:/Program Files/python/Scripts/pip.exe"'

os.system("%s list >%s" % (pip_path, tempfile1))

data = []

with open(tempfile1,"r") as f:

line_len=len(f.readlines());

f.seek(0,0)

for line in f.readlines()[2:]: #前两行为头及分割线，无需读入数组

line = line.strip("\n")

line = line.split()

data.append(line[0])

f.close()

with open(tempfile2,"w") as f:

data_len=len(data)

f.write("%s -m pip install --upgrade pip \n" % (python_path))

f.write("@rem %s install pip-review \n" % (pip_path))

f.write("@rem pip-review --auto \n")

f.write("@rem %s list >%s \n" % (pip_path, tempfile1))

f.write("@rem %s freeze >%s \n" % (pip_path, tempfile1))

for i in range(2,data_len):

f.write("%s install -U %s \n" % (pip_path, data[i]))

f.close()

os.remove(tempfile1)

os.system(tempfile2)
