string.upper(),string.lower()和string.title()方法是Python中的内置方法,用于将字符串格式化为特殊格式,例如大写,小写或小写。 1) string.upper() 1)string.upper() Method returns uppercase string (where all characters of the string are in uppercase). 方法返回大写字符串(其中字符串的所有字符均为大写...
The time complexity of the python upper function is O(n), where n is the length of the input string. This is because the function needs to iterate through each character in the string to check if it is alphabetic and convert it to uppercase if necessary. Since the function needs to che...

Python’s upper() function converts all the lowercase characters in a string to uppercase characters and returns the modified string. One common application of the upper() function in Python is to check if the given two strings are the same or not. We’ll show you how to do this using...
