exclude specific text-based values from comma separated value count and give output excluding those

Question

I want to count the ; separated values in a dataframe

solution for that can be something like this

count=[] 
for row in gdf.itertuples():
    newstr = row.info.split(";")
    n = len(newstr)
    count.append(n)

gdf["count"] = count 

However here is an issue i dont want to count those ; seperated values if they are a specific symbol, in my case its either #, ##, ### or #### so lets say for image below for id:2 i want the count to be two and for id:6 i want the count to be one and so on

failed attempts so far

• i tried stripping them before doing the count, i replaced using .replace method and # symbols were removed but the separators still stayed and made it more messier
• tried len-1 didnt worked
• i tried adding another for loop and if statement which i thought would work
  but no

count=[]                            
for row in gdf.itertuples():
        newstr = row.info.split(";")
        for i in newstr:
            if (i !='#'):
                n = len(newstr)
        count.append(n)

thanks for the help
