Adding the example code for the answer given by @CaMaDuPe85

df = pd.DataFrame({'a':[0,1,1,2,3],'b':[1,2,3,4,5],'c':[1,1,1,1,1]})
df

# df
    a   b   c
0   0   1   1
1   1   2   1
2   1   3   1
3   2   4   1
4   3   5   1


for cs in df.columns:
    print(cs,df[cs].value_counts().count()) 
    # using value_counts in each column and count it 

# Output

a 4
b 5
c 1
