The zip() function is used to zip the two values together. We can use the for loop to iterate through the list and convert each element to float type using the float() function. Mathematica cannot find square roots of some matrices? The zip() function is used to zip the two values together. In general, we know that an array is a data structure that has the capability of storing elements of the same data type in Python, whereas the list contains elements with different data type values.
