I am using Python, I have a dataframe, in the dataframe I have columns with strings and columns with floats.
some values in the cells have two symbols like this:
-0.015-0.156 ==> middle ‘-‘ is not ok, two dots not ok
0.014-0.106 ==> middle ‘-‘ is not ok, two dots not ok
0.013.0.156 ==> two dots not ok
-0.015 ==> ok
0.013 ==> ok
I want to find all the rows that have a value that is "not ok".
how can I do it?, Maybe with a condition of two dots.
