1.請在終端輸出(包括最外層雙引號):
"The language 'Python' is named afterMonty Python, not the snake."
代碼:print ('"'"The language 'Python'is named after Monty Python, not the snake."'"')
或者:print ('"'+"Thelanguage 'Python' is named after Monty Python, not the snake."+'"')
注意:輸出雙引號用單引號括起來輸出 +爲連接符
2.字符串“ don not give up. Never give up until the flight is over!”尾部感嘆號
代碼:msg=" don not give up. Never give up until the flight is over!"
print (msg[:-1])
或者:print(msg.rstrip("!"))
注意:print (msg[:-1]) 這句話沒有刪除最後一個字符的意思,是截取(術語叫做slice,切片),是指將字符串的開頭起截取到字符串末尾倒數第二個字符,並輸出,所以感嘆號沒有了
這裏,msg的值不僅是一個字符串,它是一個 String 對象,包含 rstrip() 的去尾方法,括號裏是可以寫上其他參數的,可以刪除任意符號
3.插入三個字符串(append,insert,extend)
A.extend(["wang","lin","jiao"])
臨時逆序排序(sort/sorted可以寫多個參數)
print(sorted(A,reverse=True))
插入字符串(insert)
A.insert(0,'5')
刪除值(pop(2),2爲索引值 remove移除字符)
A.pop(2)
枚舉(enumerate(p1,p2))參數p1指列表,p2代表設置索引值起始位置,默認爲0
for index,item in enumerate(A,1):
print(str(index)+'\t'+item)
