python - 如何避免字典重排键？

Question

我试图创建字典，但键总是重新排列。我希望以适当的顺序排列钥匙。在python中有可能吗？

#!/bin/python

my_val = ["vel", "acc", "force"]

my_dict=dict()
for v in my_val:
  my_dict[v] = []

for l in my_val:
  print("l = ", l) 

print("dict re-arranges")
for key in my_dict:
  print("key = ", key)

l =  vel
l =  acc
l =  force
dict re-arranges
key =  force
key =  acc
key =  vel
