Meaning of end='' in the statement print("\t",end='')? [duplicate]

This is the function for printing all values in a nested list (taken from Head first with Python).

def printall(the_list, level):
    for x in the_list:
        if isinstance(x, list):
            printall(x, level=level + 1)
        else:
            for tab_stop in range(level):
                print("\t", end='')
        print(x)

The function is working properly.

The function basically prints the values in a list and if there is a nested list then it print it by a tab space.

Just for a better understanding, what does end=' ' do?

I am using Python 3.3.5

For 2.7

f =  fi.input( files = 'test2.py', inplace = True, backup = '.bak')
for line in f:
    if fi.lineno() == 4:
        print line + '\n'
        print 'extra line'
    else:
        print line + '\n'

as of 2.6 fileinput does not support with. This code appends 3 more lines and prints the appended text on the 3rd new line. and then appends a further 16 empty lines.

Solution 1:

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

Solution 2:

See the documentation for the print function: print()

The content of end is printed after the thing you want to print. By default it contains a newline ("\n") but it can be changed to something else, like an empty string.
