1. Regular detect whether the string has upper case letters ;
2. If so, turn it to lowercase and underline it , Replace old uppercase characters with new characters ;
def turn_param_style(self, params: dict):
'''
Change the hump form of the parameter name to the underscore form
@param params:
@return:
'''
temp_dict = {}
for name, value in params.items():
temp_name = ""
if re.search("[A-Z]", name):
capital_letters = re.findall("[A-Z]", name)
for c in capital_letters:
lower_c = c.lower()
r_str = "_" + lower_c
temp_name = name.replace(c, r_str)
else:
temp_name = name
temp_dict.update({temp_name: value})
return temp_dict
Other conversion methods , here The hump characters are not converted to lowercase
Conditions that become underlined
① We can't see anything from the first one , All I know is that they are all lowercase
② From the second we get the message ： The current letter is capitalized , The first letter is lowercase , Need to add in the middle ’_’
③ From the third we get the message ： The current letter is capitalized , The first letter is also capitalized , The last letter is lowercase , You need to add... Between the current letter and the previous letter ’ _ ’
④ The resulting output is all lowercase , We regard this as a secondary factor , Finally, they are converted to lowercase
