pandas: How to get the most frequent item in pandas series?

Question

How can I get the most frequent item in a pandas series?

Consider the series s

s = pd.Series(\"1 5 3 3 3 5 2 1 8 10 2 3 3 3         


        

Answer 1

Use value_counts and select first value by index:

val = s.value_counts().index[0]

Or Counter.most_common:

from collections import Counter

val = Counter(s).most_common(1)[0][0]

Or numpy solution:

_, idx, counts = np.unique(s, return_index=True, return_counts=True)
index = idx[np.argmax(counts)]
val = s[index]
