get=(str[(str.find("id")+3):str.find(" id")])

Answer 1

您可以使用re.findall在每個order-id #之后查找數字：

import re

str = """order-id #123 order-id #234 order-id #345 order-id #456"""
re.findall(r'order-id #(\d+)', str)

輸出：

['123', '234', '345', '456']

Answer 2

如果您知道您的字符串看起來總是一樣的，您可以使用 str.split 並拆分（=刪除）您不需要的部分。 這將為您提供訂單號列表（注意！除非您更改類型，否則它們仍將是字符串）。

str = "order-id #123 order-id #234 order-id #345 order-id #456"

splitted = str.split("order-id #")
orderID = []
for item in splitted:
    if item == "":
        continue
    orderID.append(item)
print(orderID)

輸出：

['123 ', '234 ', '345 ', '456']
