I am creating a simple python file in unix, just to open and write some test in it, but getting error while execution. Using Python 2.4.3
file = open(“testfile.txt”, “w”)
file.write(“This is a test”)
file.write(“To add more lines.”)
file.close()
Error:
./test.py: line 1: syntax error near unexpected token `('
./test.py: line 1: `file = open(“testfile.txt”, “w”)'
I believe you are using curly quotes “” (e.g. from Microsoft Word, etc..) rather than actual single and double quote chars '' "".
Make sure you are using a regular text editor, not a rich text editor. That's the problem.
(' ./test.py: line 1: file = open("testfile.txt","w") 'The problem is that “ is not a valid quote in Python. Try copying and pasting this code into your file/terminal and you should then realise the difference.
file = open("testfile.txt", "w")
file.write("This is a test")
file.write("To add more lines.")
file.close()
In addition to the "smart" quotes that need to be plain ASCII " characters you need a "shebang" line as the first line of the script. Otherwise it is likely to be treated as a shell script and handed to /bin/sh for execution. You should insert this as the first line of the file:
#!/usr/bin/env python
Or run it via python ./x.py.
I think quotes are the problem. can you try a content manager
with open('testfile.txt', 'w') as output_file:
output_file.write("Your Text Here")
use of context managers is to properly manage resources. In fact, that's the reason we use a context manager . The act of opening a file consumes a resource (called a file descriptor), and this resource is limited by your OS. Similarly writing. That is to say, there are a maximum number of files a process can have open at one time.
(' ./test1.py: line 1: with open("testfile.txt", 'w') as output_file:'
