How can I check if a letter in a string is capitalized using python?
Use string.isupper()
letters = "asdfHRbySFss"uppers = [l for l in letters if l.isupper()]if you want to bring that back into a string you can do:
print "".join(uppers)
Another, more compact, way to do sdolan's solution in Python 2.7+
>>> test = "asdfGhjkl">>> print "upper" if any(map(str.isupper, test)) else "lower"upper>>> test = "asdfghjkl">>> print "upper" if any(map(str.isupper, test)) else "lower"lower
Use string.isupper() with filter()
>>> letters = "asdfHRbySFss">>> def isCap(x) : return x.isupper()>>> filter(isCap, myStr)'HRSF'
