import csv with open("price.csv","r")as f,open("price_discount.csv","w",newline="")as g: reader=csv.reader(f) writer=csv.writer(g) for row in reader: price_discount=[float(price)*0.8 for pric in row[1:]] writer.writerow([row[0]+price_discount])这段代码有什么错误

这段代码有一些错误：

1. 在 `import csv` 语句前缺少了换行符。

2. 在 `with open("price.csv","r")as f,open("price_discount.csv","w",newline="")as g:` 这行代码中，应该将 `as` 关键字放在 `open` 函数的括号后面。

3. 在 `price_discount=[float(price)*0.8 for pric in row[1:]]` 这行代码中，应该将 `pric` 改为 `price`。

4. 在 `writer.writerow([row[0]+price_discount])` 这行代码中，应该将 `price_discount` 改为 `*price_discount`，因为 `price_discount` 是一个列表，需要使用 `*` 运算符将其解包后再传递给 `writerow` 函数。

下面是修改后的代码：

import csv

with open("price.csv", "r") as f, open("price_discount.csv", "w", newline="") as g:
    reader = csv.reader(f)
    writer = csv.writer(g)
    for row in reader:
        price_discount = [float(price) * 0.8 for price in row[1:]]
        writer.writerow([row[0], *price_discount])
