"There can be zero or more :keyword:`elif` parts, and the :keyword:`else` "

"The :keyword:`for` statement in Python differs a bit from what you may be "
"used to in C or Pascal. Rather than always iterating over an arithmetic "
"progression of numbers (like in Pascal), or giving the user the ability to "
"define both the iteration step and halting condition (as C), Python's :"
"keyword:`!for` statement iterates over the items of any sequence (a list or "
"a string), in the order that they appear in the sequence. For example (no "
"pun intended):"
msgstr ""
"Satsen :keyword:`for` i Python skiljer sig lite från vad du kanske är van "
"vid i C eller Pascal. I stället för att alltid iterera över en aritmetisk "
"progression av tal (som i Pascal), eller ge användaren möjlighet att "
"definiera både iterationssteget och stoppvillkoret (som i C), itererar "
"Pythons :keyword:`!for`-sats över objekten i en sekvens (en lista eller en "
"sträng), i den ordning som de förekommer i sekvensen. Till exempel (ingen "
"ordvits avsedd):"
msgid ""
">>> # Measure some strings:\n"

msgstr "Flera andra viktiga egenskaper i detta uttalande:"
msgid ""
"Like unpacking assignments, tuple and list patterns have exactly the same "
"meaning and actually match arbitrary sequences. An important exception is "
"that they don't match iterators or strings."
msgstr ""
"Precis som uppackningsuppdrag har tuple- och listmönster exakt samma "
"betydelse och matchar faktiskt godtyckliga sekvenser. Ett viktigt undantag "
"är att de inte matchar iteratorer eller strängar."
msgid ""
"Sequence patterns support extended unpacking: ``[x, y, *rest]`` and ``(x, y, "
"*rest)`` work similar to unpacking assignments. The name after ``*`` may "
"also be ``_``, so ``(x, y, *_)`` matches a sequence of at least two items "
"without binding the remaining items."
msgstr ""
"Sekvensmönster stöder utökad uppackning: ``[x, y, *rest]`` och ``(x, y, "
"*rest)`` fungerar på liknande sätt som uppackningsuppdrag. Namnet efter "
"``*`` kan också vara ``_``, så ``(x, y, *_)`` matchar en sekvens med minst "
"två objekt utan att binda de återstående objekten."
msgid ""
"Mapping patterns: ``{\"bandwidth\": b, \"latency\": l}`` captures the "
"``\"bandwidth\"`` and ``\"latency\"`` values from a dictionary. Unlike "
"sequence patterns, extra keys are ignored. An unpacking like ``**rest`` is "
"also supported. (But ``**_`` would be redundant, so it is not allowed.)"
msgstr ""
"Mappningsmönster: ``{\"bandwidth\": b, \"latency\": l}`` fångar värdena "
"``\"bandwidth\"`` och ``\"latency\"`` från en ordbok. Till skillnad från "
"sekvensmönster ignoreras extra nycklar. En uppackning som ``**rest`` stöds "
"också. (Men ``**_`` skulle vara överflödigt, så det är inte tillåtet)"
