Counting Appearances Of Multiple Substrings In A Cell Pandas

I have a column that contains rather lengthy strings. Each of the string may or may not contain substrics. Such substrings as 'H 07', 'H 06' or 'F 13' may or may not appear in a da

Solution 1:

substrs = [...]
def f(cell_value):
    return {k: v for k, v in ((s, cell_value.count(s)) for s in substrs) if v}
df.column.apply(f)
