[FIXED] Method isupper Unicode-friendly in Python 2?

Issue

I'm using this line in my code for counting uppercase letters in a string:

text = "Áno"
count = sum(1 for c in text if c.isupper())

This code returns 0, but I expect 1 (as 'Á' is uppercase) How can I count uppercase letters with Unicode characters?

Solution

For python 2 you need to add a u, your string is not actually unicode:

text = u"Áno"

You can also write your expression as count = sum(c.isupper() for c in text), c.isupper() will return True or False so 1 or 0.

In [1]: text = "Áno"

In [2]: count = sum(c.isupper() for c in text)

In [3]: count
Out[3]: 0    
In [4]: text = u"Áno"
In [5]: count = sum(c.isupper() for c in text)    
In [6]: count
Out[6]: 1
In [7]: text = "Áno".decode("utf-8")   
In [8]: count = sum(c.isupper() for c in text)    
In [9]: count
Out[9]: 1
