Syntax error in python 2.3.4

[akilasekaran]

i am new to the python codes.. i just started out hello world.. i ended up getting an "invalid syntax" error... but i was able to run a TCP server program from the very same version of python which is python 2.3.4

Iam perplexed !!

Can you share your code here?

It could be something as simple as missing quotes.

>>> print hello world
Traceback (  File "<interactive input>", line 1
    print hello world
                    ^
SyntaxError: invalid syntax
>>> print "hello world"
hello world
>>>

I got this when i tried to run the program from cmd line.

try to put quatos after print inside of hii.py:

print "hello world"

[akilasekaran]

i still get the same error :-(

Please post the code you are using.

[akilasekaran]

>>> h="hello world"
>>> print h
hello world

[bvdet]

Remove the ">" characters and leading spaces. Your file should contain only:

h="hello world"
print h

not only this program , but in other basic programs also i get the same syntax error.. but no error comes in a this one.. i wonder how..

when i type in the python GUI i am unable to remove the >>>

may b am troublin u a lot.. :-D

[bvdet]

">>> " belongs in the interactive window but not in the file being executed.

It's strange that the code you posted works. It has several indentation errors.

[akilasekaran]

actually the hello world program worked successfull when i did it without >>> .Thanks a lot.. but now another problem..

This program i wrote for server.

from socket import *
s = socket(AF_INET,SOCK_STREAM) 
h=gethostbyname(gethostname())
print'host is ',h
s.bind((h,9000))
s.listen(1)
while 1:
    try:
    client, address = s.accept()
    print'connection from',address
    data = client.recv(1024)
    if not data:break 
        client.send(data) 
    client.close()
    
    except IOError:
        print'IOError is there !'
        client.close()

i get this following error :

D:\Python23>pyt hon serv.py
File "serv.py", line 10
print"connectio n from",address
^
SyntaxError: invalid syntax

Please use code tags when posting code. See "Need help with Bytes? (FAQ)"

Your code is not indented properly. The interpreter expects an indentation after a try statement.
