上述代码首先创建了一个名为list_data的列表,其中包含一些整数。然后,我们使用open函数打开一个名为output.txt的文本文件,该文件将在写入模式下打开。使用with语句可以确保在退出代码块时文件被正确关闭。 接下来,我们使用一个for循环遍历列表中的每个元素,并使用write方法将其写入文本文件。str(item)用于将整数转换为...
The writelines() function is used to write the contents of a list to a file. We can open the file using the open() function in the required mode. We can open the file in write or append mode in this function.For example,1 2 3 4 5 lst = ["We","Love","Python"] with open(...
#1.打开文件 file_handle =open('student.txt',mode='w') #2.写入数据 fornameinlist_1: file_handle.write(name) write在写入的时候也只能写入的是字符串,不能是数字 #写入换行符 file_handle.write('\n') #3.关闭文件 file_handle.close() #读取文件 student_list = [] 如果事先不知道文件是否存在...
Method 2: Write list to file in using Write function in Python Now let’s see another way to save list to file in Python. We are going to use the Write() function. The write() function takes string as the argument. So, we’ll be using the for loop again to iterate on each eleme...
