python - 在 Python 中创建文本文件

Question

是否可以创建一个变量来存储产品列表，而不是使用“lines”变量。创建文本文件时

#creating a textfile 

text_file= open("productlist.txt", "w")

lines = ("Bed","\n","Couch","\n","Mirror","\n","Television","\n"
         "Tables","\n","Radio")


text_file.writelines(lines)
text_file.close()

text_file = open("productlist.txt")
print(text_file.read())
text_file.close()

Answer 1

我相信您想要完成的任务是不要每次都在其中写入换行符“\n”，对吧？只需将代码放入循环即可:

#Create text file
text_file = open("productlist.txt", "w")

#Enter list of products
products = ["Bed", "Couch", "Mirror", "Television", "Tables", "Radio"] #Formerly "lines" variable

#Enter each product on a new line
for product in products:
    text_file.writelines(product)
    text_file.writelines('\n')

#Close text file for writing
text_file.close()

#Open text file for reading
text_file = open("productlist.txt")
print(text_file.read())

#Close text file
text_file.close()

如果您决定要附加到文档而不是每次都覆盖它，只需更改 text_file= open("productlist.txt", "w")到 text_file= open("productlist.txt", "a")

如果文本文档不是您列表的最佳格式，您可以考虑 exporting to a csv file (您可以在 Excel 电子表格中打开)
