python - shell脚本创建的文件不能被python打开？

Question

echo "Denied"> log.txt

稍后在python中打开log.txt:

def read_file(logs,self):
    print 'here'
    f1=open(logs,"r","utf-8")
    for line in f1:
        print str(line)

运行时报错:

"TypeError: coercing to Unicode: need string or buffer, instance found"

Answer 1

应该是:

def read_file(self, logs):

参数顺序相反

def read_file(logs, self):

您的方法尝试在您调用时打开 self 实例而不是日志:

self.read_file(logs)
