Python Practice Example 67
Topic:Input an array, swap the largest with the first element, swap the smallest with the last element, and output the array.
Program analysis:None.
Program source code:
Example
#!/usr/bin/python
# -*- coding: UTF-8 -*-
def inp(numbers):
for i in range(6):
numbers.append(int(raw_input('Enter a number:\n')))
p = 0
def arr_max(array):
max = 0
for i in range(1,len(array) - 1):
p = i
if array[p] > array[max] : max = p
k = max
array[0],array[k] = array[k],array[0]
def arr_min(array):
min = 0
for i in range(1,len(array) - 1):
p = i
if array[p] < array[min] : min = p
l = min
array[5],array[l] = array[l],array[5]
def outp(numbers):
for i in range(len(numbers)):
print numbers[i]
if __name__ == '__main__':
array = []
inp(array) # Input 6 numbers and put them into an array
arr_max(array) # Get the largest element and swap it with the first element
arr_min(array) # Get the smallest element and swap it with the last element
print 'Calculation result:'
outp(array)
The output result of the above example is:
