Most of the documentation was written prior to version 0.5 and needs to be updated. This work has now started for version 0.7 and we aim to have it completed before version 0.8 is available.

Friendly SyntaxError tracebacks - in italiano

Friendly aims to provide friendlier feedback when an exception is raised than what is done by Python.

This file contains only examples of SyntaxError and its sub-classes. Some tests may appear to be repetitive to a human reader but they are may be included to ensure more complete test coverage.

Note

The content of this page is generated by running trb_syntax_italian.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.

   2| from math import (sin, cos) as funcs
                                  ^^

I am guessing that you are trying to import at least one object
from module `math` and rename it using the Python keyword `as`;
this keyword can only be used to rename one object at a time
using a well defined syntax.
I suggest that you split up any such import statement with each object
renamed on a separate line as follows:

    from math import object_1 as name_1
    from math import object_2 as name_2  # if needed

You are using the augmented assignment operator `:=` inside
a comprehension to assign a value to the iteration variable `j`.
This variable is meant to be used only inside the comprehension.
The augmented assignment operator is normally used to assign a value
to a variable so that the variable can be reused later.
This is not possible for variable `j`.

   1| print(sum[i for i in [1, 2, 3] if i%2==0])

Python indicates that the error is caused by `[` written immediately after `sum`.
It is possible that you forgot a comma between items in a tuple,
or between function arguments,
at the position indicated by ^.
Perhaps you meant to insert an operator like `+, -, *`
between `sum` and `[`.
The following lines of code would not cause any `SyntaxError`:

    print(sum, [i for i in [1, 2, 3] if i%2==0])
    print(sum + [i for i in [1, 2, 3] if i%2==0])
    print(sum - [i for i in [1, 2, 3] if i%2==0])
    print(sum * [i for i in [1, 2, 3] if i%2==0])
Note: these are just some of the possible choices and that
some of them might raise other types of exceptions.

There is an additional possibility.
You used square brackets, `[...]` instead of parentheses.
Write the following instead:

    print(sum(i for i in [1, 2, 3] if i%2==0))

I am guessing that you were writing a comprehension or a generator expression

The correct order depends if there is an `else` clause or not.
For example, the correct order for a list comprehensions with

Python tells us that you have written an invalid number.
However, I think that the problem might be the following.

The name of a function must be a valid Python identifier,
that is a name that begins with a letter or an underscore character, `_`,
and which contains only letters, digits or the underscore character.

It looks like you used an invalid character (`8`) in an octal number.

Octal numbers are base 8 integers that only use the symbols `0` to `7`
to represent values.
In Python, octal numbers start with either `0o` or `0O`,
(the digit zero followed by the letter `o`)
followed by the characters used to represent the value of that integer.

   1| python = a b
               ^^^

Python indicates that the error is caused by `b` written immediately after `a`.
Perhaps you meant to insert an operator like `+; -; *; ,`
between `a` and `b`.
The following lines of code would not cause any `SyntaxError`:

    python = a +  b
    python = a -  b
    python = a *  b
    python = a,  b
Note: these are just some of the possible choices and that
some of them might raise other types of exceptions.

I suspect that you were trying to use a quote character inside a string
that was enclosed in quotes of the same kind.
Perhaps you should have escaped the inner quote character:

    message = 'I don\'t mind.'

Un errore di tipo `SyntaxError` accade quando Python non riesce ad interpretare il tuo codice.

Python non riesce ad interpretare il codice contenuto nel file 'TESTS:\syntax\unicode_fraction3.py'
nella posizione indicata.

   1| a = 22 ⁄ 7
             ^

Did you use copy-paste?
Python indicates that you used the unicode character `⁄`
which is not allowed.
I suspect that you used the unicode character known as
'FRACTION SLASH', which looks similar to
but is different from the division operator `/`.

Python tells us that you have written an invalid number.

I suspect that you used a fancy unicode quotation mark
whose name is SINGLE LOW-9 QUOTATION MARK.

Perhaps, you meant to write a comma.

TabError: inconsistent use of tabs and spaces in indentation

A `TabError` indicates that you have used both spaces
and tab characters to indent your code.
This is not allowed in Python.
Indenting your code means to have block of codes aligned vertically
by inserting either spaces or tab characters at the beginning of lines.
Python's recommendation is to always use spaces to indent your code.

Python non riesce ad interpretare il codice contenuto nel file 'TESTS:\syntax\unescaped_backslash.py'

   1| a = "abc\"

You started writing a string with a single or double quote
but never ended the string with another quote on that line.
Perhaps you meant to write the backslash character, `\`
as the last character in the string and forgot that you
needed to escape it by writing two `\` in a row.

Python non riesce ad interpretare il codice contenuto nel file 'TESTS:\syntax\unicode_error.py'
nella posizione indicata.

   1| path = "c:\Users\andre"
             ^^^^^^^^^^^^^^^^

I suspect that you wrote a string that contains
one backslash character, `\` followed by an uppercase `U`
and some more characters.
Python likely interpreted this as indicating the beginning of
what is known as an escape sequence for special unicode characters.
To solve the problem, either write a so-called 'raw string'
by adding the letter `r` as a prefix in
front of the string, or replace `\U`, by `\\U`.
