The below example counts the total number of vowels in the given string using the user-defined functions: # count vowels in a string# function to check character# is vowel or notdefisVowel(ch):# check the condi

print(word_lengths["pear"]) # 输出 0,因为pear不在字典中,自动使用默认值int()初始化为06.2 itertools模块 itertools模块提供了大量的高效、内存友好的迭代器生成器函数,这些函数常用于处理序列数据,尤其适用于不可变类型(如字符串、元组)的迭代操作。 •count:生成无限递增的整数序列。 import itertools counter ...
word="apple"count=10print("{0:<10}{1:>5}".format(word,count)) 1. 2. 3. 输出结果为: apple 10 1. 在上面的例子中,我们使用format()函数将变量word和count插入到字符串中。其中{0:<10}表示变量word左对齐,并使用空格进行填充,字段宽度为10;{1:>5}表示变量count右对齐,并使用空格进行填充,字段...
forword,countinword_counts.items():print(f'{word}:{count}') 1. 2. 总结 通过以上步骤,我们成功地实现了Python的词频统计功能。首先,我们导入了collections库中的Counter类。然后,我们打开并读取了待处理的文本文件。接着,我们对文本进行了一些预处理,包括去除标点符号和转换为小写。最后,我们使用Counter类统计...
