To multiply two numbers in Python, you use the*operator. For instance, if you have two variablesaandbwherea = 5andb = 3, you can multiply them by writingresult = a * b. This will store the value15in the variable
You can get the shape of a one-dimensionallistin Python, using thelen() function. This function returns the number of elements in the list, which corresponds to the size of the one-dimensional list. For example, apply this function over the given listmylist, it will return the integer(4)...
