We can convert a string to lowercase in Python using str.lower() function. In this short tutorial, we will learn how to convert to lowercase.
我们可以使用str.lower()函数将字符串转换为小写。 在这个简短的教程中,我们将学习如何将转换为小写。
Let’s look at a simple example of converting a string to lowercase and print it.
让我们看一个将字符串转换为小写并打印的简单示例。
s = '987abcDEF%$'print('Lowercase String =', s.lower())print('Original String =', s)
Output:
输出:
Lowercase String = 987abcdef%$Original String = 987abcDEF%$
Notice that when we call lower() on a string object, the original string remains unchanged. This function creates another string with lowercase characters and returns it. Special characters and numbers are unchanged because they don’t have uppercase and lowercase versions.
注意,当我们在字符串对象上调用lower()时,原始字符串保持不变。 此函数创建另一个带有小写字符的字符串并返回它。 特殊字符和数字不变,因为它们没有大写和小写版本。
Let’s have a look at another example where we will get the user input and convert it to lowercase string and print it.
让我们看另一个示例,在该示例中,我们将获取用户输入并将其转换为小写字符串并进行打印。
s = input('Please Provide Input String\n')print('Input String in Lowercase =', s.upper())print('Original String =', s)
Output:
输出:
Please Provide Input StringJava is Nice!!Input String in Lowercase = java is nice!!Original String = Java is Nice!!
