請教一個python的簡單問題

lightning

文件內(nèi)容：

Sub Main
        crt.Screen.WaitForString "Select Mode: "
        crt.Screen.Send "1" & chr(13)
        crt.Screen.WaitForString "Input group: "
        crt.Screen.Send "19" & chr(13)
        crt.Screen.WaitForString "Input device: "
        crt.Screen.Send "1" & chr(13)
        crt.Screen.WaitForString "Input accounts: "
        crt.Screen.Send "4" & chr(13)
        crt.Screen.WaitForString "assword: "
        crt.Screen.Send "12344" & chr(13)
End Sub

我希望修改 crt.Screen.WaitForString "Input device: " 下的 crt.Screen.Send "1" & chr(13) 這行中 "1" 這個數(shù)值為2或者別的數(shù)字，1這個值是會變化的，但肯定在 這一行。同時需要修改 crt.Screen.WaitForString "assword: " 這行下 crt.Screen.Send "12344" & chr(13) 中的 12344 這個值，同樣這個值是會變化的。

請教我怎么才能只修改該這兩行的值？

過過招

直接寫個，若需要函數(shù)化，可自行稍加修改。

with open('C:\\Users\\guogz\\Desktop\\1.txt') as f1, open('C:\\Users\\guogz\\Desktop\\2.txt', 'w') as f2:
    cont = f1.readlines()
    temp = [list(i) for i in enumerate(cont)]
    for ln in temp:
        if ln[1].find('Input device:') >= 0:
            lnum1 = ln[0] + 1
        elif ln[1].find('assword:') >= 0:
            lnum2 = ln[0] + 1

    orig_str1, orig_str2 = temp[lnum1][1].split()[1],  temp[lnum2][1].split()[1]
    temp[lnum1][1] = temp[lnum1][1].replace(orig_str1, '"2"')
    temp[lnum2][1] = temp[lnum2][1].replace(orig_str2, '"8888"')
    new_cont = [l[1] for l in temp]
    f2.writelines(new_cont)

haooooaaa

1. import fileinput
   
2. 
   
3. modify, next_line = {"Input device: " : 123, "assword: " : 456}, 0
   
4. 
   
5. for i in fileinput.input("c", inplace=True):
   
6.     tmp = i.split('"')
   
7.     if next_line:
   
8.         tmp[1] = str(modify[next_line])
   
9.         next_line = 0
   
10.     elif len(tmp)>1 and tmp[1] in modify:
    
11.         next_line = tmp[1]
    
12.     print '"'.join(tmp),
