I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Can you answer this question?

Sure, there are a few ways to find the maximum and minimum values in a list using Python. Here are a few examples:

Using the max() and min() functions:

The max() and min() functions are built-in functions in Python that can be used to find the maximum and minimum values in a list. The max() function takes a list as input and returns the largest value in the list. The min() function takes a list as input and returns the smallest value in the list.

For example, the following code will find the maximum and minimum values in the list list1:

Python

list1 = [10, 4, 2, 9, 7, 5, 3, 8, 6]
mavalue = max(list1)
min_value = min(list1)
print("The maximum value is", mavalue)
print("The minimum value is", min_value)

The output of the code is:

Code snippet

The maximum value is 10
The minimum value is 2

Using a for loop:

You can also use a for loop to find the maximum and minimum values in a list. The basic idea is to iterate over the list, keeping track of the largest and smallest values that you have seen so far.

For example, the following code will find the maximum and minimum values in the list list1:

Python

list1 = [10, 4, 2, 9, 7, 5, 3, 8, 6]
mavalue = list1[0]
min_value = list1[0]
for i in range(1, len(list1)):
  if list1[i] > mavalue:
    mavalue = list1[i]
  elif list1[i] < min_value:
    min_value = list1[i]
print("The maximum value is", mavalue)
print("The minimum value is", min_value)

The output of the code is the same as the previous example.

Using the enumerate() function:

The enumerate() function in Python can be used to iterate over a list and get the index of each element. This can be useful for finding the maximum and minimum values in a list, because you can use the index to keep track of which element is the largest and smallest so far.

For example, the following code will find the maximum and minimum values in the list list1:

Python

list1 = [10, 4, 2, 9, 7, 5, 3, 8, 6]
mavalue = list1[0]
min_value = list1[0]
for i, value in enumerate(list1):
  if value > mavalue:
    mavalue = value
  elif value < min_value:
    min_value = value
print("The maximum value is", mavalue)
print("The minimum value is", min_value)

The output of the code is the same as the previous two examples.
