Research in a Python dataFrame
Question
I have a dataframe composed of a column 'Letter' filled with letter going from A to Z and a column 'Lane' filled with 0 and 1. I would like to know if there is the letter H and if yes how many times on lane 0 and how many times on lane 1.
Basically I would like to know: the number of 'H' on each track (0 and 1).
In addition I would like to know how to perform a multiple search. That is to say search two letters at the same time?
Can someone please help me?

df[(df['Letter'] = 'H') & (df['Lane'] == 0)].count()
df[(df['Letter'] = 'H') & (df['Lane'] == 1)].count()
