通过 pickle 模块读取文件

Question

good afternoon, saving list(dict(),dict(),dict()) struct with pickle module: but when reading I get, <class 'function'>? and <function lesson at 0x00000278BA3A0D30> what am I doing wrong?

def lesson(user, date):
    with open(user+"_"+date+".data", 'wb') as file:
        pickle.dump(lesson, file)
    file.close()

def read(user, date):
    with open(user+"_"+date+".data", 'rb') as file:
        lesson = pickle.load(file)
    file.close()
    return(lesson)

I am using python 3.10.7

"saving list(dict(),dict(),dict()) struct with pickle module". No, you're not. You're saving the lesson function. See line 3 of your code.
