我想从文件中打印import nltk import pickle input_file=open('file.txt', 'r') input_datafile=open('newskills1.txt', 'r') string=input_file.read() fp=(input_datafile.read().splitlines()) def extract_skills(string): skills=pickle.load(fp) skill_set=[] for skill in skills: skill= ''+skill+'' if skill.lower() in string: skill_set.append(skill) return skill_set if __name__ == '__main__': skills= extract_skills(string) print(skills)但是，此处skills无法正常工作它显示错误：

_pickle.UnpicklingError：必须引用STRING操作码参数

Answer 1

必须将包含pickle数据的文件写入并读取为二进制文件。有关示例，请参阅the documentation。

您的提取功能应如下所示：

def extract_skills(path):
    with open(path, 'rb') as inputFile:
        skills = pickle.load(inputFile)

当然，您需要将数据转储到以二进制形式打开的文件中：

def save_skills(path, skills):
    with open(path, 'wb') as outputFile:
        pickle.dump(outputFile, skills)

此外，你的主要逻辑似乎有点瑕疵。虽然if __name__ == '__main__'后面的代码仅在脚本作为主模块运行时执行，但main中不的代码应该只是静态的，即定义。基本上，您的脚本不应该执行任何操作，除非以main身份运行。这是一个更清洁的版本。

import pickle

def extract_skills(path):
    ...

def save_skills(path, skills):
    ...

if __name__ == '__main__':
    inputPath = "skills_input.pickle"
    outputPath = "skills_output.pickle"

    skills = extract_skills(inputPath)
    # Modify skills
    save_skills(outputPath, skills)
