Question

我的代码从文件中获取信息并打印出相同的设计，但字符不同。例如，A.txt有一个文本文件，图像“A”由*和表示：但我需要它用大写和小写'a'打印

import os


def main():

    # relative path to the folder where you unzipped the ASCII art files
    #folder = "stars"
    # or use an absolute path to the folder. example:
    folder = r"C:\Users\sarah\Documents\a CPS 111\Bonus PA\stars\stars"

    # os.listdir(folder) returns a list of files in folder
    file_list = os.listdir(folder)
    letter_art = {}

    word = str(input("Please input a letter: "))  
    word = word.upper()

    for fname in file_list:

        letter_extension_list = fname.split(".")

    for letter in word:
        key = letter
        value = letter_extension_list[1]
        value = "%s."%(key) + value 
        letter_art[key] = value 

        fname = "\\".join([folder, value])
        print(fname)

        infile = open(fname)

        for line in infile.readlines:
            line = line.split()
            if "*" in line:
                print(word.upper())
            else:
                print(word.lower())



    infile.close()



main()

现在我的错误是

TypeError: 'builtin_function_or_method' object is not iterable

Answer 1

尝试将infile = open(fname).read()更改为infile = open(fname)

你不能readlines()来自字符串。

TypeError: 'builtin_function_or_method' object is not iterable：您应该在内置方法()之后添加readlines，基本上您正在尝试迭代此方法的返回而不是方法本身。

如果您要检查字符串中是否有line = line.split()，请同时删除*，line.split()会将line变为[line]

Answer 2

for line in infile.readlines:

readlines是一个函数，不能迭代。调用者可以调用函数并返回值。所以你只需要调用该函数并迭代它的返回值如下：

for line in infile.readlines():
    pass

更改文件中的信息以进行打印
