Learn how to compare two strings in Python and understand their advantages and drawbacks for effective string handling.
In Python, the___operator is used to compare two strings for equality. The___operator is used to check if two strings are not equal. When comparing strings, Python compares them based on their___values. Check Answers What exactly do 'u' and 'r' string flags do, and what are raw st...
猜测 There should be one-- and preferably only one --obvious way to do it. # 而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法) Although that way may not be obvious at first unless you're Dutch. # 虽然这并不容易,因为你不是 Python 之父(这里的Dutch是指Guido) Now is...
# Python program to check if a string is # palindrome or not # function to check palindrome string def isPalindrome(string): rev_string = string[::-1] return string == rev_string # Main code x = "Google" if isPalindrome(x): print(x,"is a palindrome string") else: print(x,"is...

On executing the above program, we get the following output as shown, we have compared name==rollno and their output comes as true because they have same set of elements. True Example The example given below uses the "== operator" to compare the value or equality of two object. Open...
When we run above program, it produces following result −cmp(80, 100) : -1 cmp(180, 100) : 1 cmp(-80, 100) : -1 cmp(80, -100) : 1 ExampleBut, to compare two numbers in Python 3, a user-defined function that works similar to this built-in cmp() method can be defined ...
Given two numbers n and r, find value of nCr nCr = (n!) / (r! * (n-r)!) 1. 示例: Input : n = 5, r = 2 Output : 10 The value of 5C2 is 10 Input : n = 3, r = 1 Output : 3 1. 2. 3. 4. 5. 6. # Python 3 program To calculate # The Value Of nCr def ...

Another difference between strings and lists is that strings are immutable, whereas lists are mutable. 除了这两个区别之外,字符串和列表当然也有自己的方法。 In addition to these two differences, strings and lists, of course,come with their own methods. 通常情况下,列表只包含一种类型的对象,尽管这...
