There is a small problem encountered in data analysis and data extraction. The newcomer is looking for an answer.

Today, I was working on a machine learning project and encountered a small problem. I want to extract a column of data using the regular expression
and then run it and find that there is no name1 data. This symbol is very puzzling for the Great God"s solution.


.str.extract ('^ (. +?\)')

the parentheses inside the

regular indicate that the packet is captured, but .

is not captured in your packet.
