Usage¶
Import see¶
The function named see
is all you need.
In the Python interpreter, run:
>>> from see import see
You can use a startup file to ensure that see
is always
imported when you start Python.
Inspect an object¶
-
see.
see
(obj=anything) Show the features and attributes of an object.
This function takes a single argument,
obj
, which can be of any type. A summary of the object is printed immediately in the Python interpreter. For example:>>> see([]) [] in + += * *= < <= == != > >= dir() hash() help() iter() len() repr() reversed() str() .append() .clear() .copy() .count() .extend() .index() .insert() .pop() .remove() .reverse() .sort()
If this function is run without arguments, it will instead list the objects that are available in the current scope.
>>> see() os random see() sys
The return value is an instance of
SeeResult
.
Examine the results¶
-
class
see.output.
SeeResult
(tokens) The output of the
see()
function.Acts like a tuple of strings, so you can iterate over the output:
>>> first = see()[0] >>> for string in see([]): ... print(string)
-
filter
(pattern) Filter the results using a pattern.
This accepts a shell-style wildcard pattern (as used by the fnmatch module):
>>> see([]).filter('*op*') .copy() .pop()
It also accepts a regular expression. This may be a compiled regular expression (from the re module) or a string that starts with a
/
(forward slash) character:>>> see([]).filter('/[aeiou]{2}/') .clear() .count()
-
Symbols¶
Some special symbols are used in the output from see
to show the features
of the object.
()
- Object is a function or may be called like a function.Example:
obj()
.*
- Object implements
__getattr__
, so it may allow you to access attributes that are not defined.Example:obj.anything
. []
- Object supports the
[]
syntax.Example:obj[index]
with
- Object can be used in a
with
statement.Example:with obj as target
in
- Object supports the
in
operator.Example:for item in obj
+ - * / // % **
- Object supports these arithmetic operators.Example:
obj + 1
<< >> & ^ |
- Object supports these bitwise operators.Example:
obj << 1
+obj -obj
- Object supports the unary arithmetic operators
+
(positive) and-
(negative) respectively.Example:+1
,-1
~
- Object supports the unary bitwise operator
~
(invert).Example:~1
< <= == != > >=
- Object supports these comparison operators.Example:
obj << 1
@
- Object supports the
@
operator (matrix multiplication), introduced in Python 3.5.Example:obj @ matrix
