This example demonstrates how to use the any and isalpha functions to check if a character string contains a letter from the alphabet. Let’s check our first character string my_string1: print(any(c.isalpha()forcinmy_string1))# Check if letters are contained in string# True ...
BpeTrainer 设置了我们所需的 vocab_size=6400 、 special_tokens 和一个进度条 ( show_progress=True )。 initial_alphabet 确保所有单个字节都在起始词汇表中。 现在是时候训练 tokenizer 了。 Copy# Load the text data using our generatortexts = load_texts_from_jsonl("training_data.jsonl") #your fil...
alphabet是一个字符串,它包含 ASCII 字母表的所有 26 个小写字母。调用even_items()和传递alphabet返回字母表中交替字母的列表。 Python 字符串是序列,可用于循环以及整数索引和切片。因此,对于字符串,您可以使用方括号even_items()更有效地实现相同的功能: ...

the entire alphabet is written out in reverse starting at that letter. This attack can be accelerated using a set of strips prepared with the alphabet written down in reverse order. The strips are then aligned to form the ciphertext along one row, and the plaintext should appear in one of...
