Convert a number or string to an integer, or return 0 if no argumentsn are given. If x is floating point, the conversion truncates towards zero.n If x is outside the integer range, the function returns a long instead.n n If x is not a number or if base is given, then x must ...

There are several ways to represent integers in Python. In this quick and practical tutorial, you'll learn how you can store integers using int and str as well as how you can convert a Python string to an int and vice versa.
First, though, we will need to install and import NumPy.# install numpy pip install numpy # import numpy import numpy as npNext, we will use np.array() function to convert the list of floats to integer.int_list = np.array(float_list).astype(int).tolist() print(int_list) # [1, ...
