Learn how to compare two strings in Python and understand their advantages and drawbacks for effective string handling.
Take a look at the previous output. We have created my_list1 and my_list2, two lists of strings that contain the same elements, but not in the same order. Let’s see how to compare these two lists using several methods!Example 1: Compare Two Lists With ‘==’ Operator...
enumerate方法是惰性方法,所以它只会在需要的时候生成一项,也因此在上述代码print的时候需要包装一个list。enumerate其实是一个生成器(generator),这个下面会讲到。使用enumerate之后,for循环变得很简单: for (index, item) in enumerate(items): print index, item # compare: index = 0 for item in items: print...
For example, you can compare a number and a string for equality with the == operator. However, you’ll get False as a result: Python >>> 2 == "2" False The integer 2 isn’t equal to the string "2". Therefore, you get False as a result. You can also use the != operator...

You can compare the string using Python's equality operators which are Equal To (==) and Not Equal To (!=).The Equal To (==) operators returns True if both strings are equal; False, otherwise. The Not Equal To (!=) operators return True if both strings are not equal; False, ...
The Python math.cmp() method is used to compare two numbers. This method accepts two numeric values, say x and y, as arguments and returns the sign of the difference of two numbers : -1 if x < y, 0 if x == y, or 1 if x > y....

In this example, you use the Python equality operator (==) to compare two numbers. As a result, you get True, which is one of Python’s Boolean values.Speaking of Boolean values, the Boolean or logical operators in Python are keywords rather than signs, as you’ll learn in the section...
