1, and this is confirmed by the output of lines 5 and 6. Suppose we were to reassign the identifier q. Then, unless in the interim another identifier had been assigned to q, the original “float” object would have no identifier assigned to it and so becomes inaccessible to the programmer. Python will detect this automatically and silently free up the computer memory, a process known as garbage collection. 3 The curious can find the type of an object with identifier p with the command type(p) and its identity with id(p).
There is no comma separator between items. The delimeters can be either single quotes or double quotes, but not a mixture. g. ’ Indexing and slicing work in the same way as for lists. 6). 7 Dictionaries As we have seen, a list object is an ordered collection of objects, A dictionary object is an unordered collection. Instead of accessing the elements by virtue of their position, we have to assign a keyword, an immutable object, usually a string, which identifies the element. Thus a dictionary is a collection of pairs of objects, where the first item in the pair is a key to the second.
C or Fortran. However, a Python list such as u “knows” its length, and so we could also index the elements, in reverse order, by u[len(u)-k] where k ∈ (0, len(u)], which Python abbreviates to u[-k]. This turns out to be very convenient. For example, not only is the first element of any list w referred to by w, but the last element is w[-1]. 2 shows both sets of indices for a list of length 8. Using the code snippet above, you might like to guess the objects corresponding to v and v[-3], and perhaps use the interpreter to check your answers.
