Mètodes de cadenes a Python

Alguns dels mètodes que ofereixen les cadenes són:

capitalize() – Canvia totes les lletres de cadena a majúscules.

center() – centra la cadena dins del camp d'una longitud coneguda.

count() – compta el nombre de cops que hi apareix a una cadena un caràcter donat.

join() – uneix tots els elements d'una tupla/llista en una sola cadena.

lower() – converteix totes les lletres de la cadena en lletres minúscules.

lstrip() – elimina els caràcters blancs del començament de la cadena.

replace() – substitueix una subcadena donada per una altra.

rfind() – troba una subcadena que comença des del final de la cadena;.

rstrip() – elimina els espais en blanc finals del final de la cadena.

split() – divideix la cadena en una subcadena emprant un delimitador donat.

strip() – elimina els espais en blanc inicials i finals.

swapcase() – Intercanvia les majúscules per minúscules i viceversa.

title() – fa la primera lletra en cada paraula en majúscules.

upper() – converteix totes les lletres de la cadena en majúscules.

2. String content can be determined using the following methods (all of them return Boolean values):

endswith() – does the string end with a given substring? isalnum() – does the string consist only of letters and digits? isalpha() – does the string consist only of letters? islower() – does the string consists only of lower-case letters? isspace() – does the string consists only of white spaces? isupper() – does the string consists only of upper-case letters? startswith() – does the string begin with a given substring? – joins all items of a tuple/list into one string; lower() – converts all the string's letters into lower-case letters; lstrip() – removes the white characters from the beginning of the string; replace() – replaces a given substring with another; rfind() – finds a substring starting from the end of the string; rstrip() – removes the trailing white spaces from the end of the string; split() – splits the string into a substring using a given delimiter; strip() – removes the leading and trailing white spaces; swapcase() – swaps the letters' cases (lower to upper and vice versa) title() – makes the first letter in each word upper-case; upper() – converts all the string's letter into upper-case letters.
