You can also perform string manipulation in python tofind the frequency of a characterin the string. For this, we can use thecount()method. Thecount()method, when invoked on a string, takes a character as its input argument and returns the frequency of the character as shown below. ...
我们在学法语动词变位的时候,经常会“去掉词尾” 加上xxx。这是不是很像我们最早学python玩string时候的呢?玩一玩。 直陈式现在时 有-er, -ir结尾 第一组动词, 以er结尾的 defverb_group1_indicatif_present(mot):assertmot[-2:]=='er'res={}root=mot[:-2]res['je']=root+'e'res['tu']=root+...
