下面是一个完整的代码示例,演示了如何使用Python字典找到最大值并输出相关信息: student_scores={'Alice':90,'Bob':85,'Charlie':95,'David':92}max_score=max(student_scores.values())forname,scoreinstudent_scores.items():ifscore==max_score:print(f'The student with the highest score is{name}, an...
# Finding the maximum value in a list numbers = [10, 25, 18, 40] print(max(numbers)) Output: Explanation: Here, the highest number in the list is returned using the max() function. Example 2: Python 1 2 3 4 # Finding the maximum character in an Intellipaat course name course =...

(Ctrl+F1) This inspection detects when a mutable value as list or dictionary is detected in a default value for an argument. Default argument values are evaluated only once at function definition time, which means that modifying the default value of the argument will affect all subsequent calls...
