Correct variable names consist only of English letters, digits and underscores and they can't start with a digit.
Check if the given string is a correct variable name.
Example
- For
name = "var_1__Int", the output should bevariableName(name) = true; - For
name = "qq-q", the output should bevariableName(name) = false; - For
name = "2w2", the output should bevariableName(name) = false.
我的解答：
def variableName(name):
dict = {'word':'qwertyuiopasdfghjklzxcvbnm', 'digit':'', 'underline':'_'}
if name[0].lower() in dict['word'] or name[0] in dict['underline']:
for i in name:
if i.lower() in dict['word'] or i in dict['underline'] or i in dict['digit']:
pass
else:
return False
return True
else:
return False
def variableName(name):
return name.isidentifier()
