I have a pandas dataframe with a column that contains strings of Twitter screennames eg 'JohnDoe2719'. I want to count the amount of numbers in each user name eg 4, and then create a new column in my pandas dataframe with the counts for each screenname.
Some help in this would be much appreciated.
You can use str.count
with '\d'
as regex:
df = pd.DataFrame({'name': ['JohnDoe2719', 'JohnDoe123', 'JohnDoe']})
df['count'] = df['name'].str.count(r'\d')
output:
name count
0 JohnDoe2719 4
1 JohnDoe123 3
2 JohnDoe 0
