如何从另一个脚本编写一个脚本？

Question

我需要根据用户输入执行以下函数：如果X=0，则应URL ....Print('Success将行中的内容写入文件并另存为test.py.在后端，Test.py任务调度程序会自动从保存的位置获取保存的文件 ( ) 并定期运行。是的，我们有很多例子来编写一个文件/从另一个文件运行 python，但无法从另一个文件编写 python 脚本。我肯定缺少一些基本步骤。if x=0:   ### Need to write below content to a file & save as test.py######   URL = "https://.../login"   headers  = {"Content-Type":"application/json"}   params = {   "userName":"xx",   "password":"yy"   }   resp = requests.post(URL, headers = headers, data=json.dumps(params))   if resp.status_code != 200:       print('fail')   else:       print('Success')]else:   ### Need to write below content to a file ######   URL = "https://.../login"   headers  = {"Content-Type":"application/json"}   params = {   "userName":"RR",   "password":"TT"   }   resp = requests.post(URL, headers = headers, data=json.dumps(params))   if resp.status_code != 200:       print('fail')   else:       print('Success')

Answer 1

您可以使用三引号来简化事情。

if x==0:

    path = "test.py"

    string = """\

import requests, json

URL = "https://.../login"

headers  = {"Content-Type":"application/json"}

params = {

    "userName":"xx",

    "password":"yy"

    }

resp = requests.post(URL, headers = headers, data=json.dumps(params))

if resp.status_code != 200:

    print('fail')

else:

    print('Success')

"""

else:

    path = "other.py"

    string = """\

import requests, json

URL = "https://.../login"

headers  = {"Content-Type":"application/json"}

params = {

    "userName":"RR",

    "password":"TT"

    }

resp = requests.post(URL, headers = headers, data=json.dumps(params))

if resp.status_code != 200:

    print('fail')

else:

    print('Success')

"""

with open(path, 'w') as f:

    f.write(string)

请参阅文档。大约在页面下方的三分之一处。

Answer 2

new_file = "print('line1')\n" \

           "print('line2')\n" \

           "print('line3')"

f = open('new_python.py', 'w')

print(new_file, file=f)

Answer 3

如果你想保存到文件中，最终它必须是一个字符串。

该文件的两个变体看起来非常相似，因此不要将其写入两次：

template ='''

URL = "https://.../login"

headers  = {"Content-Type":"application/json"}

params = {

   "userName":"%s",

   "password":"%s"

}

resp = requests.post(URL, headers = headers, data=json.dumps(params))

if resp.status_code != 200:

   print('fail')

else:

   print('Success')

'''

if x == 0:

    content = template % ("xx", "yy")

else:

    content = tempalte % ("RR", "TT")

with open("test.py", "w") as f:

   f.write(content)
