Hello again prospect,

Regarding your question you can find a very similar question on the forum that contains many interesting answers: A function to determine if a string is numeric, similarly How to determine if something is numeric?.

A most common way to convert a numerical string to int is casting int. For example from documentation:

For example, int(-6.725/0.025) produces -268 rather than the correct -
+269; that's because it's really more like -268.99999999999994315658 i
+nstead.
