Find Min and Max Number in Array in Python

arr = [1, 44, 21, 33, 100, 9] #'arr' is name of array.
ma = max(arr) #assigning Maximum Value of 'arr' array to 'ma'.
mi = min(arr) #assigning Minimum Value of 'arr' array to 'mi'.
print("Maximum Value is: ", ma) #and printing.
print("Minimum Value is: ", mi)

arr = [1, 1, 1] #assigning Elements to 'arr' array.
arr[1] = 2 #replacing 2 on 1 number Index Element of 'arr' array.
for num in arr: #loop looping on 'arr' Array Elements.
    print(num) #and printing.

arr = ["HiLaLs", "Khan", "Afridi", "Dara"]
del arr[2] #Deleting 2 number Index Element from 'arr' array.
for n in arr:
    print(n)

arr = list("HiLaLs") #assigning to 'arr'.
for v in arr: #loop looping on 'arr' value.
    print(v) #and printing.

arr = ["HiLaLs", "Khan", "Afridi", "Dara"]
val = arr.index("Afridi") #assigning Index of 'arr' array where is 'Afridi'.
print(val) #printing 2.
