how can i tell new python to use the old print

If you're using iPython/ Jupyter, run

% autocall 1

After that, you can use

print "yo"

While it's true that Python 2 supports, for example,

print("abc", 3)

You can use the new print function in old scripts like this:

# This line goes at the top of the file...
   from __future__
import print_function

# And then you can use the new - style print
function anywhere
print("hello")

The print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement (PEP 3105). Examples:,The print() function doesn’t support the “softspace” feature of the old print statement. For example, in Python 2.x, print "A\n", "B" would write "A\nB\n"; but in Python 3.0, print("A\n", "B") writes "A\n B\n".,PEP 3102: Keyword-only arguments. Named parameters occurring after *args in the parameter list must be specified using keyword syntax in the call. You can also use a bare * in the parameter list to indicate that you don’t accept a variable-length argument list, but you do have keyword-only arguments.,PEP 3135: New super(). You can now invoke super() without arguments and (assuming this is in a regular instance method defined inside a class statement) the right class and instance will automatically be chosen. With arguments, the behavior of super() is unchanged.

Old: print "The answer is", 2 * 2
New: print("The answer is", 2 * 2)

Old: print x, # Trailing comma suppresses newline
New: print(x, end = " ") # Appends a space instead of a newline

Old: print # Prints a newline
New: print() # You must call the
function !

Old: print >> sys.stderr, "fatal error"
New: print("fatal error", file = sys.stderr)

Old: print(x, y) # prints repr((x, y))
New: print((x, y)) # Not the same as print(x, y) !

print("There are <", 2 ** 32, "> possibilities!", sep = "")

There are < 4294967296 > possibilities!

(a, * rest, b) = range(5)

class C:
   __metaclass__ = M
   ...

class C(metaclass = M):
   ...

In this tutorial, we will learn about the Python print() function with the help of examples.,end parameter '\n' (newline character) is used. Notice, each print statement displays the output in the new line.,The print() function prints the given object to the standard output device (screen) or to the text stream file.,In the above program, only the objects parameter is passed to print() function (in all three print statements).

Example

message = 'Python is fun'

# print the string message
print(message)

# Output: Python is fun

Example

message = 'Python is fun'

# print the string message
print(message)

# Output: Python is fun

The full syntax of print() is:

print( * objects, sep = ' ', end = '\n', file = sys.stdout, flush = False)

Note: sep, end, file, and flush are keyword arguments. If you want to use sep argument, you have to use:

print( * objects, sep = 'separator')

Example 1: How print() works in Python?

print("Python is fun.")

a = 5
# Two objects are passed
print("a =", a)

b = a
# Three objects are passed
print('a =', a, '= b')

Output

Python is fun.
a = 5
a = 5 = b

Note: sep, end, file, and flush are keyword arguments. If you want to use sep argument, you have to use:

print( * objects, sep = 'separator')

not

print( * objects, 'separator')

Imagine you are building a countdown timer, which appends the remaining time to the same line every second. It would look something like below:

3 >>> 2 >>> 1 >>> Start

Most notable and most widely known change in Python 3 is how the print function is used. Use of parenthesis () with print function is now mandatory. It was optional in Python 2.,Python 2 has two versions of input functions, input() and raw_input(). The input() function treats the received data as string if it is included in quotes '' or "", otherwise the data is treated as number.,The print() function inserts a new line at the end, by default. In Python 2, it can be suppressed by putting ',' at the end. In Python 3, "end =' '" appends space instead of newline.,In Python 3, raw_input() function is deprecated. Further, the received data is always treated as string.

For example, if we want Python 3.x's integer division behavior in Python 2, add the following import statement.

from __future__
import division

Most notable and most widely known change in Python 3 is how the print function is used. Use of parenthesis () with print function is now mandatory. It was optional in Python 2.

print "Hello World"
#is acceptable in Python 2
print("Hello World") # in Python 3, print must be followed by()

The print() function inserts a new line at the end, by default. In Python 2, it can be suppressed by putting ',' at the end. In Python 3, "end =' '" appends space instead of newline.

print x, # Trailing comma suppresses newline in Python 2
print(x, end = " ") # Appends a space instead of a newline in Python 3

Python 2 accepts both notations, the 'old' and the 'new' syntax; Python 3 raises a SyntaxError if we do not enclose the exception argument in parenthesis.

raise IOError, "file error"
#This is accepted in Python 2
raise IOError("file error") #This is also accepted in Python 2
raise IOError, "file error"
#syntax error is raised in Python 3
raise IOError("file error") #this is the recommended syntax in Python 3

In Python 3, arguments to exception should be declared with 'as' keyword.

except Myerror, err: # In Python2
except Myerror as err: #In Python 3

In Python 3, print() is a function that prints output on different lines, every time you use the function. However, you can avoid this by introducing the argument end and assigning an empty string to it. This will prevent the next output from being printed in a new line.,To print without newline in Python 2.X, you have to use a comma where your print statement ends.,In order to print in the same line in Python 2.X, all you have to do is terminate your print statement with a comma.,However, unlike other programming languages that print several outputs in the same line without a new line command, Python by default prints every output on a different line.

For Example

print("Good Morning!")
print("What a wonderful day!")

Output

Good Morning!
   What a wonderful day!

In Python 3, print() is a function that prints output on different lines, every time you use the function. However, you can avoid this by introducing the argument end and assigning an empty string to it. This will prevent the next output from being printed in a new line.

# use the argument "end"
to specify the end of line string

print("Good Morning!", end = '')
print("What a wonderful day!")

2. Using "sys" Library (Python 3.X) to Print Without Newline

#Import the inbuilt sys library
import sys
#First Line of output
sys.stdout.write("Hey! Welcome to the STechies.")
#Second Line of output
sys.stdout.write("We have the best python tutorial")

Output:

Hey!Welcome to the STechies.We have the best python tutorial
