Slicing strings in a column in pandas

Question

I have a CSV that has a column of URLs and I'm trying to slice out some unnecessary characters leading and trailing characters. I'm using the following syntax:

df.['column_name'].str[3:10]

Unfortunately I get TypeError: 'method' object is not subscriptable.

Answer 1

pandas has a function to slice the entire column values, and is as follows:

df['column_name'].str.slice(start=3, stop=10)
