python - 在 Python 中验证名称的最佳方法

Question

我需要验证一个没有正则表达式的名称并保持简单，我有这个:

def validation(name):
    for char in name:
        if  not (("A" <= char and char <= "Z") or ("a" <= char and char <= "z") or (char == " ")):
            return False
    return True

有没有办法让它变得更好？

Answer 1

您需要 isalpha()方法

name = "oridm"
if name.replace(" ", "").isalpha():
    print "Name is valid"
else:
    print "Name is invalid"
