How to find a particular word in a csv file in a particular column with pandas

I want to search for a particular word in a csv file and count how many words are there , I’m using pandas to get the particular column using usecols and using str.find to search the word , but it is just returning the whole column

def read(searchitem): 
  lst = ["author"] 
  df=pd.read_csv('data.csv',usecols=lst)
  df = df["author"].str.find(searchitem)
  print(df)
  
read('IMoRT')

>Solution :

Try this:

df["author"].str.count(searchitem).sum()

EDIT:

As I understand it, you are using the same variable name for two very different things. It works, but is not recommended by best practices.

def read(searchitem): 
  lst = ["author"] 
  df=pd.read_csv('data.csv',usecols=lst)
  countWord = df["author"].str.count(searchitem).sum()
  print(countWord)
