Let’s go a step further with our code. In the above example, we used theisupper()built-in function to check if the customer’s name was already in uppercase. We could combine bothisupper()andupper()to check if
# function to check and change casedefchangeCase(str):ifstr.isupper():str=str.lower()elifstr.islower():str=str.upper()else:str=str.title()returnstr# Main codestr="HELLO WORLD"print(changeCase(str))str="hello world"print(changeCase(str))str="HELLO world"print(changeCase(str)) ...
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...
In this case, we are asking it to display an error, and Python will assume it should return a code of 1 (error encountered) since we have done this. We can use any number in this function if we want to make custom error codes. Once we have assigned our remaining list items into ...

对于训练作业,estimator.fit方法的inputs是字典,对应的每一个输入数据都是一个 Channel,Key是Channel名,Value是数据存储路径。训练作业脚本可以通过PAI_INPUT_{ChannelNameUpperCase}环境变量获取到输入数据挂载到工作容器内的数据路径。 对数据加载部分的代码进行了如下修改: ...
