Modify values of a list while iterating over it in Python? [duplicate]

Answer 1

You could use a list comprehension:

def update_single_condition(self, condition, type, params):
    condition_loaded = json.loads(condition)
    if condition_loaded['type'] == type:
        condition_loaded['params'] = params
    return json.dumps(condition_loaded)

def update_conditions(self, type, params): 
    self.conditions = [self.update_single_condition(c, type, params) for c in self.conditions]
