Hi, how are you?
I'm a Python beginner who is receiving a lot of help from hash codes.
As I process the data, I sometimes need to add or subtract some of the values of the DataFrame Series.
Is there any way to deal with this?
More specifically, I'd like to add only 5 and 8 in the "B" column.
I searched on the Internet and found that all rows or columns were combined or calculated.
I can't see is how to handle individual dataand
.I'd appreciate it if you could answer me.
And I'm always grateful to everyone who answers.
dataframe series
I don't know much about Pandas, but... If you look at the DataFrame, there is a list in the dict, so I think you can do it as follows.
"""
The result of print(df) is
{"A":[1,4,7,10], "B":[2,5,8,11], "C":[3,6,9,12], "d":[1,5,3,6]}
"""
print(df['B'][1] + df['B'][2])
