Python supports a
translate method on the
str type which allows you to specify the translation table (used for replacements) as well as any characters which should be deleted in the process.
|It is a lookup table that defines the mapping from one character to another.|
|A list of characters which are to be removed from the string.|
maketrans method (
str.maketrans in Python 3 and
string.maketrans in Python 2) allows you to generate a translation table.
>>> translation_table = str.maketrans("aeiou", "12345") >>> my_string = "This is a string!" >>> translated = my_string.translate(translation_table) 'Th3s 3s 1 str3ng!'
translate method returns a string which is a translated copy of the original string.
You can set the
table argument to
None if you only need to delete characters.
>>> 'this syntax is very useful'.translate(None, 'aeiou') 'ths syntx s vry sfl'
