Why doesn't the max method output the maximum value?

Question

Python

*********input.txt***************
100 500 1000

************************ ******
fin = open('input.txt',)
fout = open('output.txt','w')

a = []
a = fin.readline().split(' ')

fg = min(a)
fgt = max(a)
print('min =' , fg, ',' , ' max =' , fgt)

fin.close()
fout.close()

********output. txt**********
min = 100 , max = 500

******************************

Answer 1

Because you don’t have numbers, but strings, you must first translate each into a number

for i in range(len(a)):
     a[i] = int(a[i])
