我要装B一波 CentOS7 安装python的python脚本

#/bin/python

#coding=utf8

import os,sys

def choiceVersion(version):

if version == "2.7":

url = "https://www.python.org/ftp/python/2.7.16/Python-2.7.16.tgz"

download(url)

elif version == "3.7":

url = "https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz"

download(url)

else:

print("输入的版本号有误,请输入2.7或3.7")

install(version)

def download(url):

try:

cmd = "wget "+url

os.system(cmd)

except:

print("下载源码包失败,请检查当前网络")

sys.exit(1)

def install(version):

if version == "2.7":

package_name = "Python-2.7.16"

else:

package_name = "Python-3.7.2"

try:

cmd = "tar -xf "+package_name+".tgz"

os.system(cmd)

except:

print("解压源码包失败,请重新运行脚本下载源码包")

os.system("rm -rf "+package_name+".tgz")

sys.exit(1)

path = os.getcwd()

try:

dependency = "yum groupinstall -y 'Development Tools' && yum install -y zlib-devel bzip2-devel openssl-devel readline-devel libffi-devel"

os.system(dependency)

cmd = "cd "+path+"/"+package_name+" && ./configure && make && make install"

os.system(cmd)

except:

print("Python源码安装失败,请检查是否缺少依赖库")

sys.exit(1)

environmentalVariable = "echo \"PATH=$PATH:/usr/local/bin\" >> /etc/profile"

os.system(environmentalVariable)

source = "source /etc/profile"

os.system(source)

if __name__ == "__main__":

if os.getuid() == 0:

pass

else:

print("当前用户不是root,请使用root执行脚本 ")

sys.exit(1)

version_float = input("请输入你想安装的python版本 2.7或者3.7 ")

version_string = str(version_float)

choiceVersion(version_string)
