Python Pandas: How to replace a characters in a column of a dataframe?

Question

I have a column in my dataframe like this:

range

(2,30)

(50,290)

(400,1000)

... 

and I want to replace the ',' comma with '-' dash. I am currently using this method but nothing is changed.

org_info_exc['range'].replace(',','-',inplace=True)

Can anybody help?

Answer 1

Using vectorised str method replace:

df['range'] = df['range'].str.replace(',','-')

df

Output:

      range

0    (2-30)

1  (50-290)
