List comprehensions are faster



In [1]:

    
symbols = list('aeiou1234567890')
symbols









    Out[1]:





['a', 'e', 'i', 'o', 'u', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0']



In [2]:

    
%%timeit

ord_list = []
for i in symbols:
    ord_list.append(ord(i))









    



1.56 µs ± 2 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

List comprehensions are slightly faster
