在新行上打印列表元素

Question

I wish to print the elements of an array, without commas, and on separate lines. I am writing a function for insertion sort. Though it works correctly, I am finding it tricky to print them properly. The code I've written is:

#!/bin/python
def insertionSort(ar):    
    newNo = ar[-1]
    for i in range(0, m-1):
        if(newNo < ar[m-i-1]):
            ar[m-i] = ar[m-i-1]
            for e in ar:
                print e,
            print '\n'
    ar[m-i-1] = newNo
    for f in ar: print f,

m = input()
ar = [int(i) for i in raw_input().strip().split()]
insertionSort(ar)

The output I get is:

2 4 6 8 8 

2 4 6 6 8 

2 4 4 6 8 

2 3 4 6 8

I should get the following output for the code to pass the test case:

2 4 6 8 8
2 4 6 6 8
2 4 4 6 8
2 3 4 6 8

ie without the extra space between lines. Click here for the detailed problem statement.

Answer 1

print statement appends a new line automatically, so if you use

print '\n'

You will get two new lines. So you can use an empty string as in print '' or the better way would be to use print by itself :

print

Answer 2

This could be a fix -

def insertionSort(ar):    
newNo = ar[-1]
for i in range(0, m-1):
    if(newNo < ar[m-i-1]):
        ar[m-i] = ar[m-i-1]
        for e in ar:
            print e,
        print 
ar[m-i-1] = newNo
for f in ar: print f,

m = input()
ar = [int(i) for i in raw_input().strip().split()]
insertionSort(ar)

Edit - Ok ! ^ Someone already mentioned that.
