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. ...
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...

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...
How to compare strings in a case-insensitive manner? To perform a case-insensitive string comparison, you must first convert both strings to lower or upper case using the lower() or upper() string methods and then perform the string comparison. This is because lowercase and uppercase characters...
