Getting into NumPy Basics
Creating NumPy Arrays
In this section, we'll begin with the fundamentals by incorporating the NumPy library into our work and proceeding to construct our initial NumPy arrays. Renowned for their role in facilitating robust numerical computing in Python, NumPy arrays are multi-dimensional arrays that excel in efficiency. While they bear resemblance to the native list structure in Python, NumPy arrays introduce certain limitations that differentiate them from lists:
NumPyarrays are characterized by a fixed size, distinguishing them from lists which can be dynamically resized;- They also enforce a uniform data type across all elements, meaning a
NumPyarray must contain elements of the same type (e.g., exclusively integers or floating-point numbers).
These constraints are what make NumPy arrays particularly adept for specific operations, especially for element-wise operations like addition and multiplication.
Due to their ability to handle vast datasets with greater efficiency than traditional lists or data structures, NumPy arrays have become a staple in the realm of scientific computing and data analysis, enabling users to execute comprehensive operations on large data sets with ease.
Task
- Generate a one-dimensional array containing numbers from
1to5. - Form a two-dimensional array with dimensions 2x3, placing the numbers
1,2,3in the first row and4,5,6in the second row. - Construct a
NumPyarray of size 3x3 and populate it entirely with zeros.
Everything was clear?
