需要定义函数的方法,求出在列表中某个值的位置,需要有调用语句。怎么做呢,方法可以多一点!
def search_index(list, value):
return list.index(value)
list_temp = [1, 2, 3, 4, 5]
value = 5
print(search_index(list_temp, value))
import numpy as np
def find_idx(List, e):
return List.index(e)
def find_idx1(List, e):
for i in range(len(List)):
if List[i] == e:
return i
def find_idx2(List, e):
return np.where(np.array(List) == e)[0][0]
