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)." # 使用正则表达式比较 if re.fullmatch(re.escape(str1), str2): return ...
print(compare_strings_case_insensitive(str1, str2)) # 输出: True str3 = "Hello" str4 = "World" print(compare_strings_case_insensitive(str3, str4)) # 输出: False 在这个示例中,我们使用 lower 方法将两个字符串转换为小写,然后进行比较。如果相同,则返回 True,否则返回 False。 5.2 比较字符串...
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. ...
Learn how to compare two strings in Python and understand their advantages and drawbacks for effective string handling.
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.lower()方法将两个字符串都转换为小写形式,然后再进行比较。这样就实现了不区分大小写...
match(str1, str2, re.IGNORECASE): print("The strings are equal (case insensitive).") else: print("The strings are not equal.") 方法四:自定义函数 你也可以编写一个自定义函数来进行不区分大小写的字符串比较。 python def case_insensitive_compare(s1, s2): return s1.lower() == s2.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") ...
Case insensitive String compareIn 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(str1.upper()==str2.upper())...
Even though the first literal comes with a prefix, it has no effect on the outcome, so both strings compare as equal.To observe the real difference between raw and standard string literals in Python, consider a different example depicting a date formatted as a string:...
a = float('inf') b = float('nan') c = float('-iNf') # These strings are case-insensitive d = float('nan')Output:>>> a inf >>> b nan >>> c -inf >>> float('some_other_string') ValueError: could not convert string to float: some_other_string >>> a == -c # inf==...
