Try print with parenthesis in Python3 i.e. print(x) instead of print x

"print" throws an invalid syntax error in Python 3
(4 answers)
Closed 2 years ago.
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())]))

Type Error: Format Requires Mapping
(2 answers)
Closed 3 years ago.
text1="Python"
text2="with me"
print("Study %(language)s" %{'language':text1})
This works. But I am wondering whether it is using dictionary to call string?
print("Study %(language)s %(with whom)" %({'language':text1},{'with whom':text2}))
But it doesn't work. How can I fix it?
The error says 'format requires a mapping'
It would have worked, if you noticed that:
you've forgotten to put an s after %(with whom) --> %(with whom)s,
and instead of this %({'language':text1},{'with whom':text2}) --> %{'language':text1,'with whom':text2}
so the line would be like this:
print("Study %(language)s %(with whom)s" %{'language':text1,'with whom':text2})

Can I create a statement in python 2.7?
Something similar to the print statement, that it's like a function, but gets the parameters without parenthesis.

You are using Python 3, In this version print is not a keyword it is a function.
Try this :
print("hello")
