insert()
L.insert(index, object) – insert object before index
pop([index]) → item – remove and return item at index (default last).
Raises IndexError if list is empty or index is out of range.
remove()
L.remove(value) – remove first occurrence of value. Raises ValueError if the value is not present.
reverse()
L.reverse() – reverse IN PLACE
sort()
L.sort(cmp=None, key=None, reverse=False) – stable sort IN PLACE; cmp(x, y) -> -1, 0, 1
3.2.4 py.code.Frame
Frame wrappers are used in py.code.Traceback items, and will usually not directly be instantiated. They provide
some nice methods to evaluate code ‘inside’ the frame (using the frame’s local variables), get to the underlying code
(frames have a code attribute that points to a py.code.Code object) and examine the arguments.
Example (using the ‘first’ TracebackItem instance created above):
>>> frame = first.frame
>>> isinstance(frame.code, py.code.Code)
True
>>> isinstance(frame.eval(’self’), py.path.local)
True
>>> [namevalue[0] for namevalue in frame.getargs()]
[’cls’, ’path’]
class py.code.Frame(frame)
Wrapper around a Python frame holding f_locals and f_globals in which expressions can be evaluated.
statement
statement this frame is at
eval(code, **vars)
evaluate ‘code’ in the frame
‘vars’ are optional additional local variables
returns the result of the evaluation
exec_(code, **vars)
exec ‘code’ in the frame
‘vars’ are optiona; additional local variables
repr(object)
return a ‘safe’ (non-recursive, one-line) string repr for ‘object’
getargs(var=False)
return a list of tuples (name, value) for all arguments
if ‘var’ is set True also include the variable and keyword arguments when present
