熊猫的课文格式解读
熊猫的课文格式解读
提问于 2021-05-05 15:27:14
我有一张桌子的文本，我想读给熊猫听。
我可以使用\n来分隔行，但是如何将它们以格式分开(2个文本字段，然后是6x数字)。
是否有使用regex或类似的方法？

这是我讨厌的做法。但是，它依赖于有一个用"GBX“填充的货币列。
会欢迎任何关于更好的方法的想法吗？
是否有一种正则化的方法可以找到三个大写字母，前面有一个空格，然后是一个空格，然后是数字呢？这将在没有硬编码"GBX“的情况下找到这种货币。
def convert_rows(df):
sector_name = "GBX"
for index, row in df.iterrows():
if sector_name in row[0]:
name = row[0].split(sector_name)[0]
numbers = row[0].split(sector_name)[1]
df.at[index, ['Name']] = name
df.at[index, ['AIC sector']] = sector_name
df.at[index,['Price (last close)', 'Price (bid)', 'Price (offer)', 'NAV', 'Total assets (£m)', 'Market cap (£m)']] = numbers.split()
return df
df = convert_rows(df)回答 1

你可以试试这个：
import re
def convert_rows(df):
for index, row in df.iterrows():
# Search for the pattern
sector_name = re.match(r".+\s([A-Z]{3})\s\d+.+", row[0])
if sector_name:
sector_name = sector_name.group(1) # GBX for instance
name = row[0].split(sector_name)[0]
numbers = row[0].split(sector_name)[1]
df.at[index, ['Name']] = name
df.at[index, ['AIC sector']] = sector_name
df.at[index,['Price (last close)', 'Price (bid)', 'Price (offer)', 'NAV', 'Total assets (£m)', 'Market cap (£m)']] = numbers.split()
