我正在编写脚本，将字符串A添加到server1，B添加到server2，C添加到server3。
根据下面的脚本，它错误地写C到所有的服务器。请分享见解。

Python脚本：

command = []
command.append('server ')
command.append('server1 ')
command.append('server3')

output = ['A','B','C']

for i in command: 
        file = open(i +'_output.txt', 'w')
        file.close()
for j in output: 
    for i in command:
        file = open(i +'_output.txt', 'w')
        file.write(j)
        file.close()

预期输出：

server_output.txt has text "A"
server1_output.txt has text "B"
server2_output.txt has text "C"
