[英]Python - how to match specific words / digits from multiple lines in a text file and store them in separate lists
[英]Separate digits from text in Python
我正在嘗試將數字與 Python 中的字符串分開,例如以下示例:
text = "Compute the average of 5,7". (I want to get a list [5,7])
(數字之間的逗號是必須的)我試過使用:
numbers = [int(i) for i in text.split() if i.isdigit()]
當數字沒有用逗號分隔時它起作用,但是當用逗號書寫時,我只收到一個空列表。
使用正則表達式查找以逗號分隔的兩個整數。
import re
m = re.search(r'(\d+),(\d+)', text)
if m:
numbers = [int(x) for x in m.groups()]
嘗試這個:
text = "Compute the average of 5,7"
nums = [int(i) for i in text if i.isdigit()]
print(nums)
# prints [5, 7]
>>> import re
>>> re.search('.*(\d,\d).*', text).group(1)
'5,7'
