String comparison is one of the most common operations in programming. Astringcan be a collection of letters, numbers, symbols, or blank spaces. Although the way you want to compare strings depends on the use case at hand, the most common method is to compare the characters of each string ...
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. 4. 5. 6. 7. 8. ...
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. ...

For example, here's a case-insensitive【不区分大小写】 string comparison: >>> sorted("This is a test string from Andrew".split(), key=str.lower) ['a', 'Andrew', 'from', 'is', 'string', 'test', 'This'] The value of thekeyparameter should be a function that takes a single ar...

The__lt__method is used by the Python sorting functions to compare two objects. We have to compute the value of all coins in two pouches and compare them. def __str__(self): return f'Pouch with: {self.bag}' The__str__gives the human-readable representation of thePouchobject. ...
