Converting Unicode Data to Python Data
I have the following list:
list = [u'0', u'FF', u'7', u'0', u'FF', u'FFF', u'FFF']
and i need to use elements as integer or float, but when i try convevrting i get the following error:
>>> float(list[1])
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
ValueError: could not convert string to float: FF
Is there a way to solve this?

You cannot directly convert these hex values to float
, instead you can convert to int specifying the correct base using the function int()
:
>>> l = [u'0', u'FF', u'7', u'0', u'FF', u'FFF', u'FFF']
>>> [int(i,16) for i in l]
[0, 255, 7, 0, 255, 4095, 4095]
Or use float
on int
values:
>>> [float(int(i,16)) for i in l]
[0.0, 255.0, 7.0, 0.0, 255.0, 4095.0, 4095.0]
