Pandas replace string to Float

I want to remove the "HKD $" and change to Float object

I use below command line but it doesnt work.

df['price_list_1'] = df['price_list_1'].str.replace("HKD $","")

The result:

/usr/local/lib/python3.7/dist-packages/ipykernel_launcher.py:1: FutureWarning: The default value of regex will change from True to False in a future version.
  """Entry point for launching an IPython kernel.

3       $20
4       $50
       ... 
647     $58
648     $20

>Solution :

When you use .str.replace(), you should be care that if the string value includes any special characters of regular expressions such as $, ^, and *, in this case, $.

To explicity say ‘$’ is not for regular expression, you can use regex=False.

df['price_list_1'] = df['price_list_1'].str.replace("HKD $","", regex=False)
