我正在尝试学习几种语言，因此我在不同的语言上做同样的问题。这是我的代码：
def read_one_file():
with open('C:\Python27\inventory.dat', 'r') as f:
invid = f.readline().strip()
invtype = f.readline().strip()
price = f.readline().strip()
stock = f.readline().strip()
title = f.readline().strip()
author = f.readline().strip()
published = f.readline().strip()
return invid, invtype, price, stock, title, author, published
def write_one_file(holdId, holdType, holdPrice, holdStock, holdTitle, holdAuthor, holdPublished):
with open('C:\Python27\inventory.dat', 'w') as f:
invid = holdId
price = holdPrice
newstock = holdStock
published = holdPublished
f.write("Item Id: %s\n" %invid)
f.write("Item Type: %s\n" %holdType)
f.write("Item Price: %s\n" %price)
f.write("Number In Stock: %s\n" %newstock)
f.write("Title: %s\n" %holdTitle)
f.write("Author: %s\n" %holdAuthor)
f.write("Published: %s\n" %holdPublished)
return
invid, invtype, price, stock, title, author, published = read_one_file()
print "Update Number In Stock"
print "----------------------"
print "Item ID: ", invid
print "Item Type: ", invtype
print "Price: ", price
print "Number In Stock: ", stock
print "Title: ", title
print "Author/Artist: ", author
print "Published: ", published
print "----------------------"
print "Please Enter New Stock Number: "
newstock = raw_input(">")
write_one_file(invid, invtype, price, newstock, title, author, published)
。
编辑2:我最后把%d改成了%s，似乎很管用。。
最后在控制台里发生了什么
Update Number In Stock
----------------------
Item ID: 123456book
Item Type: 69.99
Price: 20
Number In Stock:
Title: Walter_Savitch
Author/Artist: 2011
Published:
----------------------
Please Enter New Stock Number:

这是.txt文件：
123456本
六十九点九九
二十
沃尔特·萨维奇
二千零一十一
有新线吗？
最佳答案
。您将f.write()、invid等定义为tuples，它们不会自动转换为字符串。You can either explicitly convert them, using the invtype function, or more likely what you'd like is to use some string formatting, e.g.:
"Number in stock%d"%nrStock
其中，“%d”表示nrStock是一个整数。
