How can I find all differences of two consecutive values from a list?

Question

'''
I have a list of thousands value, it looks like that:
c = [9.00205, 9.00394, 9.00582, ...]
'''
#My empty attempt:

if i in c while i<len(c): (i)-(i+1)

It would be good if it is lambda function.

THANKS!

Answer 1

It's completed.
The answer is
all_diff = [j-i for i, j in zip(c[:-1], c[1:])]
