How to map mutiple keys to single value in pandas?

Question

a = pd.Series([1,2,3,4,5])
a.replace({1:10 , 3:10 , 5:10})

Instead of repeating it each time , is there any way to combine keys to replace the values.

Answer 1

Use list:

b = a.replace([1,3,5], 10)
print (b)
0    10
1     2
2    10
3     4
4    10
