If you define a value without decimals, Python will interpret it as an integer, and if you specify values that include decimals will be interpreted as floating-point numbers. Python print float To print float values in Python, use the print() function. The print() is a built-in function that prints the defined message to the screen … Read more
The ceil() is a built-in Python function that rounds a number up to the nearest integer. There is one more function called floor(), which we will see, and then we will know the difference between int() and floor() function. Python int() The int() is a built-in Python that converts a specified value into an integer … Read more
There are two types of numbers in Python. integers floating-point The integers are either positive numbers, negative numbers, or 0. Commonly referenced as int. The floating-point numbers can contain decimals, whereas integers cannot. To convert a number stored in a string or integer convert into a floating-point number, use the float() function. The math.floor() function in Python … Read more
In Python, there is no null value. Instead, it has None. The None or empty string, empty list, False – all are considered as falsy values. Checking falsy values sometimes becomes tricky as it gives unexpected results. Python does not have a built-in function or operator to check null coalesce but you can use still … Read more

There are two types of the file path. Relative path: Use “/” to get the relative path. Absolute path: Use the os.getcwd() function to … Read more
Arrays are not native data types in Python. To use an array in Python, we need to use the numpy library. For large arrays, a vectorized numpy operation is the fastest. np.arange The np.arange() function returns an array with evenly spaced elements as per the interval. To use the np.arange() method in your Python script, you have … Read more
To work with an array in Python, use the numpy library. The numpy provides an important data type called a ndarray. np.arange To create an array based on numerical routines in Python, use the np.arange() function. The numpy.arange() function returns an instance of ndarray with evenly spaced values. import numpy as np arr = np.arange(start=0, stop=10, … Read more
