Linked List In Data Structures Types Of Linked Lists Applications Since a list comprehension creates a list, it shouldn't be used if creating a list is not the goal; it shouldn't be used simply to write a one line for loop; so refrain from writing [print(x) for x in range(5)] for example. Is there a way in python to list all installed packages and their versions? i know i can go inside python lib site packages and see what files and directories exist, but i find this very awkward. The first way works for a list or a string; the second way only works for a list, because slice assignment isn't allowed for strings. other than that i think the only difference is speed: it looks like it's a little faster the first way. try it yourself with timeit.timeit () or preferably timeit.repeat (). Another common mistake is to initialize a list but try to assign values to it using a key. the initialization probably happened dynamically and it's not clear later on that it's in fact a list. for example, in the following case, d is initialized as a list but there's an attempt to add a key value pair to it.

When reading, list is a reference to the original list, and list[:] shallow copies the list. when assigning, list (re)binds the name and list[:] slice assigns, replacing what was previously in the list. also, don't use list as a name since it shadows the built in. What is the syntax to insert one list into another list in python? [duplicate] asked 14 years, 10 months ago modified 6 years, 1 month ago viewed 349k times. For handling a few strings in separate variables, see how do i append one string to another in python?. for the opposite process creating a list from a string see how do i split a string into a list of characters? or how do i split a string into a list of words? as appropriate. 134 isin() is ideal if you have a list of exact matches, but if you have a list of partial matches or substrings to look for, you can filter using the str.contains method and regular expressions. for example, if we want to return a dataframe where all of the stock ids which begin with '600' and then are followed by any three digits:.
