file_path = 'example.json' # 调用函数读取JSON文件 json_data = read_json_file(file_path) # 打印JSON数据 print(json_data) 上述代码中,首先导入了json模块。然后定义了一个read_json_file函数,该函数接受一个文件路径作为参数,使用open函数打开文件,并使用json.load方法将文件内容解析为JSON格式的数据。最后...
file_path = 'path/to/your/file.json' try: with open(file_path, 'r', encoding='utf-8') as file: data = json.load(file) print(data) except FileNotFoundError: print(f"File not found: {file_path}") except json.JSONDecodeError: print(f"Error decoding JSON from the file: {file_pa...
Example 2: Python read JSON file You can use json.load() method to read a file containing JSON object. Suppose, you have a file named person.json which contains a JSON object. {"name": "Bob", "languages": ["English", "French"] } Here's how you can parse this file: import jso...
read() # 读取全部内容 print(content) 逐行读取: with open('example.txt', 'r', encoding='utf-8') as file: for line in file: print(line.strip()) # 去除每行末尾的换行符 逐行读取到列表: with open('example.txt', 'r', encoding='utf-8') as file: lines = file.readlines() # 返回...
首先,读取JSON文件内容到字符串中: import json# 读取文件内容到字符串中with open('data.json', 'r', encoding='utf-8') as file:json_str = file.read()# 使用json.loads()方法解析JSON字符串data = json.loads(json_str)# 打印解析后的Python对象print(data)print(data['name']) # 提取name字段的...

步骤1:读取JSON文件 首先,我们需要将JSON文件读取到一个字符串中。我们可以使用Python的内置函数open()来打开文件,并使用.read()方法读取文件内容。 # 打开JSON文件withopen('example.json','r')asfile:# 读取文件内容json_str=file.read() 1. 2.
