How to filter pandas dataframe by a feature value ending with Case sensitive letter

I have a data frame like this:
df:

C1    C2
Ford  11
ram   13
SUV   19
SEDAN 14

I want to filter the data frame column C1 where the C1 values end with a upper case character. So the expected output looks like this:

C1    C2
SUV   19
SEDAN 14

I tried different regex approaches but nothing worked out for me.

Can anyone help me with this?

>Solution :

str.endswith doesn’t accept regexes, use str.contains:

df[df['C1'].str.contains('[A-Z]$')]

Output:

      C1  C2
2    SUV  19
3  SEDAN  14
