Check if the input is a number using int() or float() in Python Theint()orfloat()method is used to convert any input string to a number. We can use this function to check if the user input is a valid number. If the user input is successfully converted to a number usingint()orfl...
4. isdigit() and replace() to Find if a String is Float Another way to check if a string is a valid float is to use theisdigit()andreplace()methods. Theisdigit()method checks if all the characters in a string are digits, while thereplace()method replaces a specified character in a...
In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...

我们可以直接从常见的标记器(如GPT-2和ALBERT (A Lite BERT)标记器)调用预标记化方法。这些方法与上面所示的标准BERT预标记器略有不同,因为在分割标记时不会删除空格字符。它们被替换为表示空格所在位置的特殊字符。这样做的好处是,在进一步处理时可以忽略空格字符,但如果需要,可以检索原始句子。GPT-2模型使用Ġ字...
