Do you mean any specific syntax for wildcards? Usually * stands for "one or many" characters and ? stands for one.

The simplest way probably is to translate a wildcard expression into a regular expression, then use that for filtering the results.

Use fnmatch   import fnmatch lst     this   is   just   a   test   filtered   fnmatch filter lst   th s     If you want to allow   as a wildcard  just replace all underscores with      for one character  or    for multiple characters    If you want your users to use even more powerful filtering options  consider allowing them to use regular expressions

Why don t you just use the join function  In a regex findall   or group   you will need a string so   import re regex   re compile  th s   l     this    is    just    a    test   matches   re findall regex      join l    Syntax option 1 matches   regex findall     join l    Syntax option 2   The join   function allows you to transform a list in a string  The single quote before join is what you will put in the middle of each string on list  When you execute this code part      join l   you ll receive this    this is just a test   So you can use the findal   function   I know i am 7 years late  but i recently create an account because I m studying and other people could have the same question  I hope this help you and others     Update After  F  lixBrunet comments   import re regex   re compile r th s   l     this    is    just    a    test   th   s    this is    matches2     declare a list for i in range len l     loop with the iterations   list l lenght  This avoid the first item commented by  Felix if regex findall l i           if the position i is not an empty list do the next line  PS  remember regex findall   command return a list      if l i       join regex findall l i       If the string of i position of l list   command findall   i position so it ll allow the program do the next line - this avoid the second item commented by  F  lix         matches2 append    join regex findall l i      adds in the list just the string in the matches2 list  print matches2

You could try the fnmatch module  it s got a shell-like wildcard syntax  or can use regular expressions  import re

Regular expressions are probably the easiest solution to this problem   import re regex   re compile  th s   l     this    is    just    a    test   matches    string for string in l if re match regex  string

Same idea as Yuushi in using regular expressions  but this uses the findall method within the re library instead of a list comprehension   import re regex   re compile  th s   l     this    is    just    a    test   matches   re findall regex  string
