Python Mode Example | Python Statistics Module
Python mode() is an inbuilt function in a statistics module that applies to nominal (non-numeric) data. The mode() is used to locate the central tendency of numeric or nominal data. Python statistics module has a considerable number of functions to work with very large data-sets. The mode() function is one of such methods. The mode is a value at which the data is most likely to be sampled.
Python Mode Function Example
If you are looking for the most occurring number in list, array, or tuple then Python mode() function is the answer you are looking for.
The mode is the statistical term that refers to the most frequently occurring number found in a set of numbers. The mode is detected by collecting and organizing data to count the frequency of each result.
In Python, we use the Statistics module to calculate the mode. See the following example.
# app.py import statistics listA = [19, 21, 46, 19, 18, 19] print(statistics.mode(listA))
In the above code, number 19 is frequently appearing. So that is our mode.
See the below output.
Now, let’s see the unique item list.
# app.py import statistics listUnique = [19, 21, 18, 30, 46] print(statistics.mode(listUnique))
The above list has unique elements inside the list. So mode does not work here. Instead, it will give us an error.
See the below output.
Calculate Mode of Tuple in Python
Let’s define a tuple and calculate the mode of Tuple.
# app.py import statistics data = (21, 19, 18, 46, 30, 18, 19, 21, 18) print(statistics.mode(data))
Let’s see the output.
Let’s add more examples to the app.py file.
# app.py import statistics from fractions import Fraction as fr data1 = (1, 2, 2, 3, 3, 3, 4, 4, 4, 4) print(statistics.mode(data1)) data2 = (2.1, 1.9, 2.1, 1.8, 2.9) print(statistics.mode(data2)) data3 = (fr(19, 21), fr(18, 21), fr(19, 21), fr(21, 46)) print(statistics.mode(data3)) data4 = (-21, -22, -21, -29, -18, -19) print(statistics.mode(data4)) data5 = ('Emily', 'Matt', 'Ross', 'Rachel', 'Monica', 'Chandler', 'Rachel') print(statistics.mode(data5))
See the output below.
It will work with Strings as well, as we have defined the list of Strings in the last example.
