## no unique mode; found 2 equally common values

calculate mode in python list

I would like to use `statistics.mode([1,1,2,2,3])` function in python to calculate the mode, it returns `no unique mode; found 2 equally common values`. In this way, I would like to output either `1` or `2`. Does anyone have any good idea?

For example:

```lst = [1, 1, 2, 2, 3]

# test for count lst elements
lst_count = [[x, lst.count(x)] for x in set(lst)]
print lst_count
# [[1, 2], [2, 2], [3, 1]]

# remove count <= 1
lst_count = [x for x in set(lst) if lst.count(x) > 1]
print lst_count
# [1, 2]

# get 1 or 2 by index
print lst_count[0], lst_count[1]
# 1 2
```

Another way:

```from collections import Counter

# change lst elements to str, for more readable
lst = ['a', 'a', 'b', 'b', 'c']

# get a dict, key is the elements in lst, value is count of the element
d_mem_count = Counter(lst)
print d_mem_count
# Counter({'a': 2, 'b': 2, 'c': 1})

for k in d_mem_count.keys():
if d_mem_count[k] > 1:
print k

# output as below
# a
# b
```

no unique mode; found 2 equally common values, For example: lst = [1, 1, 2, 2, 3] # test for count lst elements lst_count = [[x, lst.​count(x)] for x in set(lst)] print lst_count # [[1, 2], [2, 2], [3,  A unique mode is the most occurring number in a set of data. For example, since the set: {1,2,2,4,4,5} does not have a single most occurring data value, the two modes (2 and 4) are averaged to

Try this function, which finds the max values as mode when no unique mode:

```import statistics
def find_max_mode(list1):
list_table = statistics._counts(list1)
len_table = len(list_table)

if len_table == 1:
max_mode = statistics.mode(list1)
else:
new_list = []
for i in range(len_table):
new_list.append(list_table[i][0])
max_mode = max(new_list) # use the max value here
return max_mode

if __name__ == '__main__':
a = [1,1,2,2,3]
print(find_max_mode(a)) # print 2
```

Statistics in Python using the statistics module, The four functions we'll use in this post are common in statistics: mean - average value; median - middle value; mode - most often value mode([1, 1, 2, 2, 3]) StatisticsError: no unique mode; found 2 equally common values. The mode function will return the modal value only if the distribution has a unique mode. If the distribution has multiple modes, python raises StatisticsError; For Example, the mode() function will report “ no unique mode; found 2 equally common values” when it is supplied of a bimodal distribution.

```from collections import Counter
c = Counter([1,1,2,2,3])
c.most_common(1)
# output
>>> [(1,2)] #the key 1, 2 occurrences.
```

From the docs:

"most_common([n]): Returns a list of the n most common elements and their counts from the most common to the least. Elements with equal counts are ordered arbitrarily"

Python statistics, The mode of a set of data values is the value that appears most often. It is the value at which StatisticsError: no unique mode; found 2 equally common values. \$\begingroup\$ Generally speaking the mode is not defined to be unique. If two or more values tie as most frequently occuring they both or all are modes. It is unconventional to pick one of the modes and call it "the mode".

```from scipy import stats as s
a=[1,1,2,2,3]
print(int(s.mode(a)[0]))
```

A (simple) more flexible implementation of the mode function than , statistics.mode(data). Traceback (most recent call last): statistics.StatisticsError: no unique mode; found 2 equally common values. >>> calc_mode(freq_tab=ft). The mode of a set of data values is the value that appears most often.It is the value at which the data is most likely to be sampled. A mode of a continuous probability distribution is often considered to be any value x at which its probability density function has a locally maximum value, so any peak is a mode.

I just faced the same issue. This how I solved it pretty simply:

```def most_element(liste):
numeral=[[liste.count(nb), nb] for nb in liste]
numeral.sort(key=lambda x:x[0], reverse=True)
return(numeral[0][1])
```

Not sure this the most elegant way but it does the job :). Hope it will help
