python -拍卖脚本(从文件输入到字典)

Question

所以我有一个文件，例如：

Book
Peter 500
George Peterson 300
Notebook
Lizzie 900
Jack 700

整数是他们的奖品。我想读一下名字和字典的标书，但我被困在这里：

d = {}
with open('adat.txt') as f:
    d = dict(x.rstrip().split(None, 1) for x in f)
for keys,values in d.items():
    print(keys)
    print(values)

那么，如何正确地读取数据呢？

Answer 1

您需要跳过“无效”行，如Book和Notebook。

d = {}
with open('adat.txt') as f:
    for line in f:
        words = line.split()
        try:
            price = int(words[-1])
            name = ' '.join(words[:-1])
            d[name] = price
        except (ValueError, IndexError):
            # line doesn't end in price (int() raised ValueError)
            # or is empty (words[-1] raised IndexError)
            pass

for key, value in d.items():
    print(key)
    print(value)
