Friendly SyntaxError tracebacks - in English¶
Friendly-traceback aims to provide friendlier feedback when an exception is raised than what is done by Python. This file contains only examples of SyntaxError. Ideally, an example of each case handled by friendly-traceback should be included here.
Note
The content of this page is generated by running
trb_syntax_english.py located in the tests/ directory.
This needs to be done explicitly, independently of updating the
documentation using Sphinx.
On Windows, if Sphinx is installed on your computer, it is suggested
instead to run make_trb.bat in the root directory as it will create
similar files for all languages and update the documentation.

My best guess:
You wrote an expression like

where <1>, on the left hand-side of the equal sign, is
or includes an actual number or string (what Python calls a 'literal'),
and not the name of a variable. Perhaps you meant to write:

My best guess:
Python gave us the following informative message
about the possible cause of the error:
closing parenthesis ']' does not match opening parenthesis '('
However, I do not recognize this information and I have
to guess what went wrong, but I might guess incorrectly.
The closing square bracket ']' on line 2 does not match the opening parenthesis '(' on line 2.

beyond the location indicated below by --> and ^.
1: """Should raise SyntaxError: Missing parentheses in call to 'print' ..."""
-->2: print 'hello'
^
My best guess:
Perhaps you need to type print('hello')?
In older version of Python, 'print' was a keyword.
Now, 'print' is a function; you need to use parentheses to call it.
SyntaxError - Python keyword as function name¶
Python exception:
SyntaxError: invalid syntax
A SyntaxError occurs when Python cannot understand your code.
Python could not parse the file 'TESTS:\syntax\raise_syntax_error21.py'
beyond the location indicated below by --> and ^.
1: """Should raise SyntaxError: invalid syntax"""
2:
-->3: def pass():
^
My best guess:
Python did not give us much information regarding
the cause of the error. I make an effort below to guess what
went wrong, but I might guess incorrectly.
You tried to use the Python keyword 'pass' as a function name.
SyntaxError - break outside loop¶
Python exception:
SyntaxError: 'break' outside loop
A SyntaxError occurs when Python cannot understand your code.
Python could not parse the file 'TESTS:\syntax\raise_syntax_error22.py'
beyond the location indicated below by --> and ^.
1: """Should raise SyntaxError: 'break' outside loop"""
2:

2:
-->3: message = 'don't'
^
My best guess:
Python did not give us much information regarding
the cause of the error. I make an effort below to guess what
went wrong, but I might guess incorrectly.
There appears to be a Python identifier (variable name)
immediately following a string.
I suspect that you were trying to use a quote inside a string
that was enclosed in quotes of the same kind.

a function call and not the name of a variable.
SyntaxError - used equal sign instead of colon¶

My best guess:
Python did not give us much information regarding
the cause of the error. I make an effort below to guess what

In Python, you can define functions with only positional arguments

def test(a=1, b=2, c=3): ...
or a combination of the two
def test(a, b, c=3): ...

you have another string, which starts with either a
single quote (') or double quote ("), without a matching closing one.
SyntaxError - unclosed bracket¶

3:
4:
5: def f(x):

My best guess:
You are including the statement
global x
indicating that 'x' is a variable defined outside a function.
You are also using the same 'x' as an argument for that
function, thus indicating that it should be variable known only
inside that function, which is the contrary of what 'global' implied.
SyntaxError - keyword as attribute¶

I am guessing that you forgot to enclose some content in a string.
SyntaxError - keyword can’t be an expression¶
Python exception:
SyntaxError: expression cannot contain assignment, perhaps you meant "=="?

4: """
5:
-->6: a = dict('key'=1)

My best guess:
One of the following two possibilities could be the cause:
1. You meant to do a comparison with == and wrote = instead.
2. You called a function with a named argument:
a_function(invalid=something)
where 'invalid' is not a valid variable name in Python
either because it starts with a number, or is a string,
or contains a period, etc.
SyntaxError - invalid character in identifier¶
