列表转换成文件

f = open("Information.txt","w+",encoding="utf8")
Information = [["1","alex","IT"],["2","bob","IT"]]
User_Choice = int(input("Your choice is:"))
for i in Information:
    if User_Choice == int(i[0]):
       Information.remove(Information[User_Choice])
       for j in Information:
           f.write(‘,‘.join(j).strip()) #关键是这一步，把列表通过join方法转换成字符串，然后再写入文件
           f.close()
