如何将这些 python 行作为列表理解？

Question

我需要帮助，如何将这些行写为列表理解

   t_averaged = []
   for i in range(len(i_averaged)-1):
     t_av = t[i_averaged [i] ]+ time_intervall /2
     t_averaged.append(t_av )

Answer 1

它应该是

t_averaged = [
    t[i_averaged[i]] + time_intervall/2
        for i in range(len(i_averaged)-1)
] 

并且没有range(len(...))

t_averaged = [
    t[item] + time_intervall/2
        for item in i_averaged[:-1]
]
