max value and index python code example

Example 1: python index of max value in list

# any list
a = [1, 7, 3, 12, 5]

# index of minimum element
# if more than 1 minimum, 
# first index is returned
min_index = a.index(min(a))

# index of maximum element
max_index = a.index(max(a))

Example 2: get index of highest value in array python

result = numpy.where(arr == numpy.amax(arr))

Example 3: max value in python

# find largest item in the string
print(max("abcDEF")) 

# find largest item in the list
print(max([2, 1, 4, 3])) 

# find largest item in the tuple
print(max(("one", "two", "three"))) 
'two'

# find largest item in the dict
print(max({1: "one", 2: "two", 3: "three"})) 
3

# empty iterable causes ValueError
# print(max([])) 

# supressing the error with default value
print(max([], default=0))

Example 4: # get the largest number in a list and print its indexes

numbers = 1,3,11,42,12,4001
highestnumber = -999
for i in numbers:
  if i > highestnumber:
    highestnumber = i
print(numbers.index(highestnumber))
