Python only integers, slices ... and integer or boolean arrays are valid indices

import numpy as np
import matplotlib.pyplot as plt
from scipy.integrate import odeint
from scipy import integrate
from scipy.optimize import fmin

Td=np.array([0.5,1,1.5,2,2.2,3,3.5,4,4.5,5])#time
findindex=lambda x:np.where(mt>=x)[0][0]
mindex=map(findindex,Td)

Zm=Td[mindex]

When I try to run this code it throws an exception.

Exception has occurred: IndexError only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices.

I am new in Python. Can someone help to solve this.

IIUC you want to filter the index meet some criteria and then slice the numpy array using those indexes

mt=3
Td[np.where(Td<mt)] # where values in Td array less than mt get indexes and slice the array
