def compare_strings(str1, str2): # 直接比较 if str1 == str2: return "The strings are identical." # 忽略大小写比较 if str1.casefold() == str2.casefold(): return "The strings are identical (case insensitive)." # 使用正则表达式比
from functools import cmp_to_key def compare_strings(str1, str2): if str1 < str2: return -1 elif str1 > str2: return 1 else: return 0 strings = ["banana", "apple", "cherry"] sorted_strings = sorted(strings, key=cmp_to_key(compare_strings)) print(sorted_strings) 三、利用local...
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,让我们通过一个简单的函数来判断两个字符串是否在内容上相同,而不考虑大小写: defcompare_strings_case_insensitive(str1,str2):returnstr1.lower()==str2.lower()result=compare_strings_case_insensitive("Apple","apple")print(result)# 输出: True 1. 2. 3. 4. 5. 在这个函数中,我们使用了str....
Learn how to compare two strings in Python and understand their advantages and drawbacks for effective string handling.
Case insensitive String compare In case you want to compare String by case insensitive, you need to use either upper() or lower() with Strings. 1 2 3 4 5 6 7 str1="hello" str2="HELLO" print(str1.lower()==str2.lower())
print("The strings are not equal (case insensitive)") 5. 使用str.__eq__()方法 str.__eq__()方法用于比较两个字符串是否相等,这个方法等同于使用==运算符。 示例代码 str1 = "apple" str2 = "banana" if str1.__eq__(str2): print("The strings are equal") ...
normalize() can be used to perform string comparisons that won't falsely report inequality if two strings use combining characters differently: import unicodedata def compare_strs(s1, s2): def NFD(s): return unicodedata.normalize('NFD', s) return NFD(s1) == NFD(s2) single_char = 'ê' ...
It will count occurrences of substrings even if they are part of other words. Case Sensitivity: The method is case-sensitive, requiring additional steps for case-insensitive counting. No Regular Expression Support: Unlike methods in the re module, str.count() does not support regular expressions...
