题目二 - Compare Strings Compare two strings A and B, determine whether A contains all of the characters in B. The characters in string A and B are all Upper Case letters. Example For A = "ABCD", B = "ABC", return true. For A = "ABCD" B = "AABC", return false. 1. 2. 3....
例如: defstarts_with_A_case_insensitive(string):returnstring.lower().startswith('a')# 测试print(starts_with_A_case_insensitive("Apple"))# 输出: Trueprint(starts_with_A_case_insensitive("apple"))# 输出: Trueprint(starts_with_A_case_insensitive("Banana"))# 输出: False 1. 2. 3. 4. ...
print("The strings are equal") 2. 使用str.compare()方法 虽然Python 3已经弃用了str.compare()方法,但仍然可以在Python 2中使用它来进行字符串比较,该方法返回一个整数,表示比较的结果,如果返回值为0,则两个字符串相等;如果返回值小于0,则左侧字符串小于右侧字符串;如果返回值大于0,则左侧字符串大于右侧字符...

case_insensitive = re.findall(r"search", text, re.IGNORECASE) print(case_insensitive) 12. Using Named Groups To assign names to groups and reference them by name: match = re.search(r"(?P<first>\w+) (?P<second>\w+)", text) if match: print(match.group('first')) print(match.gro...
>>> sorted([5, 2, 4, 1, 3], cmp=numeric_compare) [1, 2, 3, 4, 5] 或者你可以反序排序: >>> def reverse_numeric(x, y): return y - x >>> sorted([5, 2, 4, 1, 3], cmp=reverse_numeric) [5, 4, 3, 2, 1]
# Compare insensitively return dict(self.lower_items()) == dict(other.lower_items()) # Copy is required def copy(self): return CaseInsensitiveDict(self._store.values()) def __repr__(self): # print 的时候会进入 print(isinstance(self.items(), Iterable)) # 输入可迭代对象,此时 ##内部...
2. 不要贪多,选一个知名度高的Python教程,教学为辅,练习为主。每天用15分钟学习课程,剩余时间就用来做编程练习好了。要随时记住,我们学习Python的目的在于会用,而不是背过了多少知识点。 嘻嘻,这里给大家推荐一个我挺喜欢的python课程——夜曲编程。我刷了一些编程题目,竟回想起,当年备考雅思时被百词斩支配的恐...
"" return ( (lowerkey, keyval[1]) for (lowerkey, keyval) in self._store.items() ) def __eq__(self, other): if isinstance(other, Mapping): other = CaseInsensitiveDict(other) else: return NotImplemented # Compare insensitively return dict(self.lower_items()) == dict(other.lower_...
