Count number of times observation appears row wise pandas?

Question

If I have a dataframe like this:

Area	Favorite Fruit
UT	Banana
TN	Grape
VT	Banana
AZ	Banana
CA	Cherry

I want to insert a column with a count for how many times the fruit appears across the df like so:

Area	Favorite Fruit	Fruit Count
UT	Banana	3
TN	Grape	1
VT	Banana	3
AZ	Banana	3
CA	Cherry	1

Trying to do this in python.

Answer 1

Use transform('size'):

df['Fruit Count'] = df.groupby('Favorite Fruit')['Favorite Fruit'].transform('size')

Answer 2

Try with value_counts + reindex

df['Fruit Count'] = df['Favorite Fruit'].value_counts()\
                   .reindex(df['Favorite Fruit']).values
