Each pair has the form (condition, event). If we were processing the entire Brown Corpus by genre, there would be 15 conditions (one per genre) and 1,161,192 events (one per word) Counting Words by Genre按类型统计单词 In Section 2.1, we saw a conditional frequency distribution where the...

In this example, because number = 42, the conditions are true, and all() returns True. You can play with the value of number if you’d like to experiment a bit. In the final two examples, you use the callable() function. As its name suggests, this function allows you to determine ...
The Python guidance on package and module names focuses on short names with lowercase letters, relying on other characters where needed for readability. Underscore use for these names is generally discouraged. For class names, use the CamelCase style. Use all lowercase letters separated by ...
