如何根據條件逐行讀取文件並將其寫入文件。 在python中

Question

我想逐行讀取文件，首先對第一個值執行一些操作，然后再次從文件中讀取第二個值，想要執行一些操作，例如，如果我有一個文件，其值是Vik John Lisa

我想一一閱讀並傳遞到sql server，然后根據性別在文件中寫入輸出（年齡）。如果以Vik開頭的名字是男性，則在文件male.txt中輸入他的年齡，否則在female.txt中。這個

代碼 ：

with open('C:\code\out.txt', 'r') as content_file:
  for line in content_file:
    cs=pyodbc.connect('Trusted_Connection=yes', driver = '{SQL Server}',server = '.', database = 'Test')
    tablequery="select Age,Gender from dbo.AuditSource where Name='" + line+"'";
    cursor = cs.cursor()
    cursor.execute(tablequery)
    rows = cursor.fetchall()
    for row in rows:
        age=row.Age
        Gen=row.Gender
        print(age)
        if Gen=='M':
            with open('C:\code\male.txt', 'a') as f:
                f.write(age) #here getting error not able toe write var value

        else:
            with open('C:\code\female.txt', 'a') as f:
                f.write(age) #here getting error not able toe write var value

Answer 1

這是您要的代碼。

search = open("some.txt","r") #opens and read file        
for line in search:
   new  = line[0]
   if new == "V":
      file = open("edit.txt","w")
      file.write(line)
