python split(python中split方法怎么用)

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計出這篇文章有多少個單詞,某個單詞出現的次數,從而可以統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="MynameisMonkeyDLufy.Themanwhoisgoingtobethekinginthesea."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","nameisMonkeyDLufy.Themanwhoisgoingtobethekinginthesea."]["My","name","is","Monkey","D","Lufy.","The","man","who","is","going","to","be","the","king","in","thesea."]["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。
