# 关闭文件以保存数据file.close() 1. 2. 完整代码示例 下面是完整的代码示例,把上述步骤合起来: # 定义一个包含几种水果的列表fruits=["apple","banana","orange","grape","kiwi"]# 打开文件,文件名为 fruits.txt,模式为 'w' 表示写入模式file=open("fruits.txt","w")# 遍历列表中的每个水果,并将...
在上面的代码中,我们首先定义了一个save_list_to_file函数,该函数接受两个参数:列表和文件路径。在函数内部,我们使用with open(file_path, 'w') as file语句打开文件,并使用for item in lst语句遍历列表中的每个元素。然后,我们使用file.write(str(item) + '\n')将每个元素转换为字符串,并写入文件。 方法...

Chapter 4. Persistence: Saving data to filesIt is truly great to be able to process your file-based data. But what happens to your data when you’re done? Of course, it’s best to save your data to a disk file, which allows you to use it again at some later date and time. ...
在此示例中,我们使用 numpy 模块的 savetxt() 函数将列表存入文本文件。 importnumpyasnp list1 = [1,2,3] np.savetxt('Python.txt',list1) print(open("Python.txt").read()) # 输出: 1.000000000000000000e+00 2.000000000000000000e+00 3.000000000000000000e+00...
