python - 为什么我会收到此错误？ '_io.TextIOWrapper' 对象没有属性 'append'

Question

为了解决这个错误，我已经做了很多事情，但我已经干涸了。有人知道为什么我总是收到此错误吗？

myList =[n, weather, wind, other, avgscore]
    with open("data.txt", 'w') as f:
        for s in myList:
            f.append(str(s) + '\n')
    print("Thank you, your data was logged")

Answer 1

您需要使用 write() 而不是 append():

myList =['n', 'weather', 'wind', 'other', 'avgscore']
with open("list.txt", 'w') as f:
    for s in myList:
        f.write(str(s) + '\n')
print("Thank you, your data was logged")

如果您想将数据 append 到已写入的文件而不是覆盖它:

You need to open the file in append mode, by setting "a" or "ab" as the mode.

docs:

myList =['n2', 'weather2', 'wind2', 'other2', 'avgscore2']
with open("list.txt", 'a') as f:
    for s in myList:
        f.write(str(s) + '\n')
print("Thank you, your data was logged")

输出:

n
weather
wind
other
avgscore
n2
weather2
wind2
other2
avgscore2
