NoneType对象没有属性计数

Question

我对此有疑问 它一直在说：NoneType对象没有属性计数

def failListiks(failinimi):
    with open(failinimi) as f:   
        listina = f.readlines()
        print(listina)
    return

minulist = failListiks("sonad.txt")
tahtedearv = minulist.count("a")
print(tahtedearv)

Answer 1

failListiks返回None。我怀疑您想返回行列表，但是您只是在打印它们。进行以下更改：

def failListiks(failinimi):
    with open(failinimi) as f:   
        listina = f.readlines()
        print(listina)
        return listina # return the lines
