How to use user-defined Function In Python
Here we are not using any predefines functions for getting mode of a series. Let us see an example with demonstrates how to calculate mode without predefined functions.
Example :
Python3
# creating a listlst = [1, 2, 3, 4, 5, 6, 2, 3, 4, 5, 5, 5, 5]# defining a function to calculate mode. It # takes list variable as argumentdef mode(lst): # creating a dictionary freq = {} for i in lst: # mapping each value of list to a # dictionary freq.setdefault(i, 0) freq[i] += 1 # finding maximum value of dictionary hf = max(freq.values()) # creating an empty list hflst = [] # using for loop we are checking for most # repeated value for i, j in freq.items(): if j == hf: hflst.append(i) # returning the result return hflst# calling mode() function and passing list# as argumentprint(mode(lst)) |
Output :
[5]
How to Calculate the Mode of NumPy Array?
In this article, we will discuss how to calculate the mode of the Numpy Array.
Mode refers to the most repeating element in the array. We can find the mode from the NumPy array by using the following methods.
