Unicode in String

Python 3's string is a sequence of unicode characters. You do not need the u in u"…", but you can add it for familiarity with python 2. The u has no meaning.

Unicode Characters in Variable and Function Names

Python 3 allows Unicode characters in variable and function names, but they must be letter characters. Non-letter characters are not allowed. [see What Characters Are Unicode Letter]

def φ(n):
    return n + 1

α = 4
print(φ(α))
# 5

♥ = 4

print(♥)

#     ♥ = 4
#     ^
# SyntaxError: invalid character in identifier
error: cannot format -: '♥'
