創(chuàng)新互聯(lián)Python教程：解析python split()方法的用法及實例代碼
能夠把一個字符分解成多個子字符，串聯(lián)在一起后，在進行應用，這一系列過程，在大家學習編程里會想到什么呢？今天就給大家介紹能實現(xiàn)這一作用的split方法
split()方法的作用
是按指定的分隔符，把一個字符串分隔成指定數目的子字符串，然后把它們放入一個列表中，然后應用。
實際應用
比如有一篇文章，我們可以把它當做一個字符串，然后用split()分隔成一個一個的單詞組成的列表，這樣我們把這個列表導出到Excel中，或者其他的工具中，然后就可以非常容易的統(tǒng)計出這篇文章有多少個單詞，某個單詞出現(xiàn)的次數，從而可以統(tǒng)計出哪些單詞是高頻詞，然后我們可以用這些數據干很多事情。
實例展示
long_string="My name is Monkey D Lufy. The man who is going to be the king in the sea."
str_list1=long_string.split()
str_list2=long_string.split(" ",1)
str_list3=long_string.split(" ",16)
str_list4=long_string.split(" ",17)
str_list5=long_string.split(" ",20)
print(str_list1)
print(str_list2)
print(str_list3)
print(str_list4)
print(str_list5)運行結果
["My","name","is","Monkey","D","Lufy.","The","man","who","is","going","to","be","the","king","in","the","sea."] ["My","name is Monkey D Lufy. The man who is going to be the king in the sea."] ["My","name","is","Monkey","D","Lufy.","The","man","who","is","going","to","be","the","king","in","the sea."] ["My","name","is","Monkey","D","Lufy.","The","man","who","is","going","to","be","the","king","in","the","sea."] ["My","name","is","Monkey","D","Lufy.","The","man","who","is","going","to","be","the","king","in","the","sea."]
關于split()方法總結
1）split()有兩個參數，第一個參數是分隔符，如果不指定，則默認以空格、換行、制表符為分隔符，第二個參數為分隔次數，如果不指定，則跟據字符串中有多少個分隔符，就分隔多少次。
2）str_list2指定空格為分隔符，只分隔1次，所以在My和name之間分隔一次，后面的都不分隔。
3）long_string這個字符串中總共有17個空格，如果指定分隔次數大于17，則Python也不會報錯，還是以分隔符的總數進行分隔。
相信大家通過實例演示，已經掌握了關于split()方法技巧了吧，除此之外strftime()函數、random()函數、range()函數等大家可以點擊鏈接查詢了解~
