checking the unique values counts pandas code example
Example 1: count unique pandas
df['column'].nunique()
Example 2: count how many unique rows a DataFrame has
df = pd.DataFrame(np.random.randint(0,2,size = (10,3)))
df
0 1 2
0 1 1 1
1 1 0 1
2 1 1 1
3 1 0 0
4 1 1 1
5 1 0 1
6 0 0 1
7 0 1 1
8 0 1 0
9 0 0 1
# the only unique rows are : 3, 7 and 8
df.duplicated(keep = False) == False
0 False
1 False
2 False
3 True
4 False
5 False
6 False
7 True
8 True
9 False
dtype: bool
# so to count how many unique rows we have:
sum(df.duplicated(keep = False) = False)
