Syntax error on print with Python 3 [duplicate]

def creating_table():
mailingTable = open("mailingTable.txt", "r")
lines = mailingTable.readline()
for line in lines:
print line
mailingTable.close()
It says print line is invalid syntax. Why? I m using python 3.3.5
In Python 3.x, you have to write print() as follows, because now it's a function:
print(line)
In Python 2.x it was possible to omit the (), but that's no longer the case.

What does the colon on words_pron_dict:str mean? I am getting syntax error on python 2.7. Is it python 3? How can i use it?
class TextToSpeech:
CHUNK = 1024
def __init__(self, words_pron_dict:str = 'cmudict-0.7b.txt'):
self._l = {}
self._load_words(words_pron_dict)
It's a type annotation: https://docs.python.org/3/library/typing.html
You should be able to just remove it.

"print" throws an invalid syntax error in Python 3

This is for Python 2:
import re
print sum([int(i) for i in re.findall('[0-9]+',open(raw_input('What is the file you want to analyze?\n'),'r').read())])
But why do I get a syntax error with Python 3?
Python3
import re
print sum([int(i) for i in re.findall('[0-9]+',open(input('What is the file you want to analyze?\n')).read())])
That is because in Python3 you should use brackets around the argument for the print function.
print()
so your code will work as soon as you write
print(sum([int(i) for i in re.findall('[0-9]+',open(input('What is the file you want to analyze?\n')).read())]))

You would do something like this in python:
with open(filename, 'r') as f:
for line in f:
print(line)

I'm getting the following error:
File "foo.py", line 6
print "This implementation requires the numpy module."
^
SyntaxError: invalid syntax
In this Python code:
#!/usr/bin/python
try:
import numpy
except:
print "This implementation requires the numpy module."
exit(0)

if __name__ == "__main__":
R = [
[1,2,3],
[4,5,6]
]
What is wrong?
EDIT: I use Python 3.3
This should be:
print("....")
Starting with python 3, print is a function, not a special case statement.
