Split String into List and Convert to Integer What happens if you're working with a string-represented list of integers? After splitting, you won't be able to perform integer operations on these, since they're ostensibly strings. Thankfully, we can use the sameforloop as before to convert...
# 字符串的劈分操作 split# 1. split从字符串左侧开始分割,默认值为空格字符串,返回值是一个列表# 以通过参数sep指定劈分字符串是劈分符# 通过maxsplit指定劈分字符串的最大劈分次数s = 'hello#world#python'lst = s.split('#')print(lst)s1 = 'hello|world|python'print(s1.split())print(s1.split...
Return a list of the words in the string, using sep as the delimiter string. sep The delimiter according which to split the string. None (the default value) means split according to any whitespace, and discard empty strings from the result. maxsplit Maximum number of splits to do. -1 (...
function takes the first argument as a type String and second argument base. You can pass in the string as the first argument, and specify the base of the number if it is not in base 10. Theint()function can also handle negative integers by recognizing the negative sign in the string....

>>> string_value = "I like to sort" >>> sorted_string = sorted(string_value.split()) >>> sorted_string ['I', 'like', 'sort', 'to'] In this example, you use .split() to convert the original sentence into a list of words. Afterward, you sort the list instead of individual ...
names.sort(key=lambda e: e.split()[-1]) First, we sort the names by their first names. Then we sort the names by their last name. To do so, we split each string and choose the last string (it has index -1.) Since Python's sort algorithm is stable, the first sorting is remem...
