Python pandas: oposite of pandas.Series.str.match

How to Determine if each string in a column does not start with a match of a regular expression.

I need to check when a Column does NOT equal a string.

I've found:

pandas.Series.str.match

And it is almost what I need, but I want to get True when the string is NOT a match

You can check with pd.Series.str.startswith

df_sub = df[~df['col'].str.startswith('your str')]

Just negate the mask returned by str.contains:

~df['col'].str.contains("Your string")
