Python get abs()函数的字典值

# 定义一个包含数字的字典
my_dict = {'a': -5, 'b': 10, 'c': -15}

# 获取字典中某个键对应的值的绝对值
key = 'a'
absolute_value = abs(my_dict[key])

print(f"The absolute value of {key} is {absolute_value}")

The absolute value of a is 5

# 获取字典中所有值的绝对值
absolute_values_dict = {key: abs(value) for key, value in my_dict.items()}

print(absolute_values_dict)

{'a': 5, 'b': 10, 'c': 15}
