上述代码首先导入了json模块,然后创建了一个包含不同数据类型的列表list_data。 接下来,我们使用open函数打开一个名为output.txt的文本文件,并在写入模式下打开。使用with语句可以确保文件在使用后被正确关闭。 最后,我们使用json.dump函数将列表list_data写入文本文件中。json.dump函数将自动将列表转换为JSON格式并写入...
with open('output.txt', 'w') as file: # 后续步骤将在这里进行 使用with语句可以确保文件在操作完成后被正确关闭,即使在写入过程中发生异常也是如此。 遍历列表中的每一个元素: 使用for循环来遍历列表。 python my_list = [1, 2, 3, 'four', 'five'] for item in my_list: # 后续步骤将在这里...
首先,我们需要准备一个list,准备将其写入到文件中。 # 准备一个listmy_list=[1,2,3,4,5] 1. 2. 2. 打开文件 接下来,我们需要打开一个文件,以便将list写入其中。 # 打开一个文件,使用写入模式file=open('output.txt','w') 1. 2. 3. 将list转换为字符串 在将list写入文件之前,我们需要先将list转...
