python 写list进文件 python write list 在讲列表的“增删改查”之前,我们先来讲解什么叫做列表。 举个例子: namelist = [] #定义一个空的列表 namelist = ["小明", "小红", "小张"] print(namelist[0]) print(namelist[1]) print(namelist[2]) 1. 2. 3. 4. 5. 运行结果: 小明 小红 小张 1. ...
Now, let me show you how to write a list to file in Python using different methods with examples. Method 1: Write a List to a File Using write() The simplest way to write a list to a file is by using thewrite()method in Python. This method involves converting the list to a strin...
def write_list_to_file(lst, file_path): with open(file_path, 'w') as file: for item in lst: file.write(str(item) + '\n') 这段代码定义了一个write_list_to_file函数,接受一个列表lst和一个文件路径file_path作为参数。函数使用open函数打开文件,并以写入模式('w')打开。然后,使用for循环遍...
file.close() 1. 完整示例 下面是一个完整的示例代码,将列表数据写入文件中: file=open("data.txt","w")data=[1,2,3,4,5]foritemindata:file.write(str(item)+"\n")file.close() 1. 2. 3. 4. 5. 6. 7. 以上就是使用Python将列表数据写入文件的完整过程。 序列图 NewbieDeveloperNewbieDevelope...

1. Using write method: #!/usr/bin/python l1=['hi','hello','welcome'] f=open('f1.txt','w') for ele in l1: f.write(ele+'\n') f.close() The list is iterated, and during every iteration, thewritemethod writes a line to a file along with the newline character. ...

readlines() # 逐行读取文件中的内容,将读取的内容放在一个list列表中 !## :一次性读取文本内容,速度比较快,随着文本的增大,占用内存会越来越多 file = open(r"C:\Users\11764\Desktop\国内镜像源.txt",encoding="utf-8") file.readlines() file.close() ...
