Question

我有一个用于生成批处理文件的python代码，输入来自txt文件

def create_bat_file(lp=None):
  with open(r"test.txt", "r+") as file:
    currentDir = os.path.abspath(".")
    data = file.readlines()
    for line in data:
      a = line.split('=')
      b = a[0]
      f = a[1]
      bk = a[2]
      reldat = a[3]
      f= open("{}.bat".format(f),"w+")
      f.write("@ECHO OFF\n")
      f.write("SET lp="'"{}"'"\n".format(lp))
      if b == "RB":
          f.write("SET reldat="'"{}"'"".format(reldat))
      if b == "RB":
        f.write("{}\\a.exe POST -d "'"best.variable.lp=lp"'"" " " "{}".format(currentDir,bk))
      else:
        f.write("{}\\a.exe POST -d "'"best.variable.cp=cp"'"" " " "{}".format(currentDir,bk))
      f.close()

test.txt文件的输入内容不足

RB=TEST14=https://test.com.org/rest/api/latest/queue/TEST-RR=2017-12-06

下面是输出

@ECHO OFF
SET lp="test"
SET reldate="2017-12-06
"C:\a.exe POST -d "best.variable.cp"=cp https://test.com.org/rest/api/latest/queue/TEST-RR

问题是何时创建批处理文件（TEST14.bat）

Wrong:

SET reldate="2017-12-06
    "C:\a.exe POST -d "best.variable.cp"=cp https://test.com.org/rest/api/latest/queue/TEST-RR

在输出中，双引号结尾是下一行它应该总是像

Correct:

SET reldate="2017-12-06"
C:\a.exe POST -d "best.variable.cp"=cp https://test.com.org/rest/api/latest/queue/TEST-RR

line的最后一个字符是换行符\n。 reldat的最后一个字符也是换行符。因此，就行：

f.write("SET reldat="'"{}"'"".format(reldat))

您最终在最后一个\n之前添加了"。

要解决此问题，您可以从\n中剥离line并在需要的地方添加缺失的一个：

def create_bat_file(lp=None):
  with open(r"test.txt", "r+") as file:
    currentDir = os.path.abspath(".")
    data = file.readlines()
    for line in data:
      line = line[:-1]  #### STRIP NEWLINE CHARACTER ####
      a = line.split('=')
      b = a[0]
      f = a[1]
      bk = a[2]
      reldat = a[3]
      f= open("{}.bat".format(f),"w+")
      f.write("@ECHO OFF\n")
      f.write("SET lp="'"{}"'"\n".format(lp))
      if b == "RB":
          f.write('SET reldat="{}"\n'.format(reldat))  #### ADD MISSING NEWLINE ####
      if b == "RB":
        f.write("{}\\a.exe POST -d "'"best.variable.lp=lp"'"" " " "{}".format(currentDir,bk))
      else:
        f.write("{}\\a.exe POST -d "'"best.variable.cp=cp"'"" " " "{}".format(currentDir,bk))
      f.close()

我还自由地在字符串周围使用单引号，看起来好多了！

生成具有正确输出python的bat文件？
