【Python】.pyファイルにある関数とメソッドを全て取得する

はじまり

今回のソース

今回のソースはこちらになります。読み取り先ファイルと読み取り元ファイルを同じディレクトリに配置して、この読み取り元ファイル.pyを実行します。

get_words_in_lines_by_head_and_tail()で、"def "と"("の間の文字列を取得します。

そして、remove_head_spaces()で、取得した文字列の"def "より前にある空白文字を削除します。

読み取り元ファイル.py

def remove_head_sapces(word : str, spaces : list = [" ", "　"]) -> str:
    word_removed_space = ""
    if len(word) == 0:
        word_removed_space = word
    elif word[0] in spaces:
        word_removed_space = word[1:len(word)+1]
        # invisible head character if head space is nothing
        print("'{}'".format(word_removed_space[1:len(word)]))
        word_removed_space = remove_head_sapces(word_removed_space, spaces)
    else:
        word_removed_space = word
    return word_removed_space

    print(text_lines)

    for text_line in text_lines:

        head_index = text_line_removed_head_space.find(head_of_target, 0)
        if head_index != 0:
            continue
        tail_index = text_line_removed_head_space.find(tail_of_target, 0+head_index)

print(actual)

読み取り先ファイル.py

class ReplaceCharacter:
    def make_voicedsound(self, text : str) -> str:
        pass

def main():
    replace_character = ReplaceCharacter()

if __name__ == "__main__":
    main()

出力
