python 3.0 "with" syntax error?

Question

i have a syntax error with the with statement. i cant figure it out. i am using python 3 and every time i use the with statement it just wont have it. i am trying to make a reader for a txt file and i need this with statement.

import csv

value1 = "Spam"

fname = input(open("Please enter the name of the file you wish to open: ")

with open(fname, 'rb') as csvfile:
    spamreader = csv.reader(csvfile, delimiter=' ', quotechar='|')
    for row in spamreader:
        if value1 in row:
            print(" ".join(row))

i am very new to python its probably very obvious cheers for the help guys

Aside: if you're opening a csv file in Python 3, you should use open(fname, 'r', newline='') instead of open(fname, 'rb') (which is how you did it in Python 2.) See the docs. — DSM

The syntax error is not caused by with, but print statement. In Python 3.x, print is a function.

>>> print 1
  File "<stdin>", line 1
    print 1
          ^
SyntaxError: invalid syntax
>>> print(1)
1
>>>

So the following line:

print " ".join(row)

should be replaced with:

print(" ".join(row))

In the following sentence, a parenthesis is missing.

fname = input(open("Please enter the name of the file you wish to open: "))
#                                                                         ^

And open should be omitted:

fname = input("Please enter the name of the file you wish to open: ")

@user3077551: please edit the entire traceback into your question. Possibly you have an unclosed parenthesis on an earlier line.
