Hướng dẫn print without space python

You can use the sep parameter to get rid of the spaces:

>>> print["a","b","c"]
a b c
>>> print["a","b","c",sep=""]
abc

I don't know what you mean by "Java style"; in Python you can't add strings to [say] integers that way, although if a and b are strings it'll work. You have several other options, of course:

>>> print["a = ", a, ", b = ", b, sep=""] 
a = 2, b = 3
>>> print["a = " + str[a] + ", b = " + str[b]]
a = 2, b = 3
>>> print["a = {}, b = {}".format[a,b]]
a = 2, b = 3
>>> print[f"a = {a}, b = {b}"]
a = 2, b = 3

The last one requires Python 3.6 or later. For earlier versions, you can simulate the same effect [although I don't recommend this in general, it comes in handy sometimes and there's no point pretending otherwise]:

>>> print["a = {a}, b = {b}".format[**locals[]]]
a = 2, b = 3
>>> print["b = {b}, a = {a}".format[**locals[]]]
b = 3, a = 2

Introduction

The print[] function in Python appends a newline to the output when displayed on the tty [teletypewriter A.K.A the terminal]. When you don't want your message displayed with newlines or with spaces, how can you change the behavior of print[]?

This can easily be achieved by altering the default values of the sep and end parameters of the print[] function.

Printing Without a Newline

Until Python version 2.x, print was a reserved keyword that acts as a special statement. Since Python version 3.x, the print command has evolved into a function.

This version of print[] is capable of taking the following arguments:

The values [value1, value2] mentioned above can be any string or any of the data types like list, float, string, etc. The other arguments include a separator [sep] used to divide the values given as arguments whereas the argument end is the \n newline character by default. This is the reason why whenever the print[] function is called, the cursor slides to the next line.

In Python 3.x, the most straightforward way to print without a newline is to set the end argument as an empty string i.e. ''. For example, try executing the following snippet in your Python interpreter:

print["I am a sentence", "I am also a sentence"]

The interpreter would output the following:

I am a sentence I am also a sentence
>>>

We are printing two strings, so Python will use the value of sep, a blank space by default, to print them together. Python also adds a newline character at the end, so the interpreter prompt goes to the end line.

Now modify the previous statement to look like this:

print["I am a sentence", "I am also a sentence", sep="; ", end=""]

Upon executing it in the interpreter, you will get an output resembling:

I am a sentence; I am also a sentence>>>

Two things happened here - the separator between the two strings now also includes a semicolon. The interpreter prompt also appears on the same line because we removed the automatically appended newline character.

Printing Without a Newline in Python 2.X

For earlier versions of Python - less than 3 but greater than 2.6 - you can import print_function from the __future__ module. This will override the existing print keyword with the print[] function as shown below:

from __future__ import print_function

print["I am a sentence", "I am also a sentence", sep="; ", end=""]

This will also yield:

I am a sentence; I am also a sentence>>>

This is how you can use Python version 3's print[] function in Python 2.x.

Using stdout.write[]

The sys module has built-in functions to write directly to the file or the tty. This function is available for Python 2.x and 3.x versions. We can use the write[] method of the sys module's stdout object to print on the console like this:

import sys

sys.stdout.write["I am a line"]

Let's execute this and take a look at the output:

I am a line>>>

Although this gives the output of what we are trying to achieve, there are quite a few differences between the write[] function and the print[] function. The print[] function can print multiple values at a time, can accept non-string values, and is friendlier to developers.

Conclusion

In this article, we have explored the different ways by which values can be printed without a newline character/carriage return. This strategy can come quite handy while printing the elements in the outputs of algorithms such as a binary tree or printing the contents of a list next to each other.
