Python 通过Pythion替换不同文件夹中阵列的某些部分 我的代码将替换整个文件。而我只需要一些替代品。 下面是我试图替换的文件。我只想更改“sheetname”中的一些单词：“Main” 我试图做的是替换“Main”“sheet”中的某些单词，即sheetname=Main； 提前谢谢。任何帮助都会很好！ 下面是我的代码：

将文件中的数据命名为

数据

这是一个json数据，如果您将其保存在一个文件中，则可以使用json模块加载该数据，并简单地进行迭代，然后添加您的条件

import json
import os
import sys

directory = os.listdir('/Users/Unicorn/Desktop/for all/change')
os.chdir('/Users/Unicorn/Desktop/for all/change')

for file in directory:
    open_file = open(file,'r', encoding='utf-8')
    read_file = open_file.read()
    open_file.close()
    # loads json file so it can be treated just like dictionary/list object in python
    data_json = json.loads(read_file)

    # iterate sheet item in data
    for sheet in data_json:
        # this is where you put your condition for sheetname == "Main"
        if sheet['sheetname'] == 'Main':
            # iterate over emp_detail because it is a list
            for emp_detail in sheet['emp_details']:
                # this is my simple method to replace item on a list
                if 'Gaurav' in emp_detail:
                    emp_detail[emp_detail.index('Gaurav')] = 'Singh'
    data_final = json.dumps(data_json)
    open_file = open(file,'w', encoding='utf-8')
    open_file.write(data_final)
    open_file.close()

您需要替换哪些数据？例如，对于“Main”到Singh的Gaurav。您的意思是“sheetname”中的“Gaurav”：“Main”到“Singh”？是的，它应该只在“sheetname”：“Main”中更改。嗨，仅使用粗体字体或标题有点像喊叫。使用

#

作为标题以更好地显示文章的结构是很好的，但是在所有文章中始终使用它们可能被视为不礼貌。不需要在这里修复它，但请在下一篇文章中克制自己。实际上，它正在工作，也不工作。我的意思是它在这种情况下工作得很好，但是日语字符变成了某种unicode。我还想得到输出文件的设计。但是非常感谢。我不知道为什么，但是代码不起作用。谢谢你的帮助。@Rubin你有什么错误吗？我已经在你列出的数据上测试过了<代码>数据需要一个字典列表。你能添加一个完整的代码吗，可能是因为我在什么地方弄错了。对不起打扰了@鲁宾将字典的赋值列表添加到变量

数据中

我这样做了。导入json word_to_replace='Gaurav'new_word='Singh'和open（'new.json'，'r'，encoding='utf-8'）作为文件：data=json.load（file）用于data:if dictionary.get（'sheetname'）=='Main'：…（复制了代码）。。。。。。。。。dictionary['emp_details']=打开（'wow.json'，'w'，encoding='utf-8'）为文件的新_数据：json.dump（data，file，indent=4）问题是日语字符变成/u。。。像那样。
