Question

def read_contents(self,filename):
    with open(filename,'r') as f:
        lines=f.read().splitlines()
        print lines

s=read_contents('input.txt')

当试图运行这个程序时，会抛出错误，因为需要两个参数并且self需要作为参数之一出现（这是更大代码的一部分）如何将filename作为参数传递而不会出现错误

Answer 1

您必须在课程中使用它：

class Test:
    def read_contents(self, filename):
        with open(filename, 'r') as f:
            lines = f.read().splitlines()
            print lines

test = Test()
s = test.read_contents('input.txt')

或删除自我：

def read_contents(filename):
    with open(filename, 'r') as f:
        lines = f.read().splitlines()
        print lines

s = read_contents('input.txt')

我如何通过自我传递参数
