import pandas as pd ds = pd.Series([1,3,5,7,9,11,13,15], index=[0,1,2,3,4,5,7,8]) print("Original Series:") print(ds) print("\nIndex of 11 in the said series:") x = ds[ds == 11].index print(x)
Original Series: 0 1 1 3 2 5 3 7 4 9 5 11 7 13 8 15 dtype: int64 Index of 11 in the said series: 5

Python: Tips of the Day
Measure the execution time of small bits of Python code with the "timeit" module.
import timeit print(timeit.timeit('"-".join(str(n) for n in range(100))', number=100000)) print(timeit.timeit('"-".join([str(n) for n in range(100)])', number=100000)) print(timeit.timeit('"-".join(map(str, range(100)))', number=100000))
