python关键词词频统计

可以使用Python内置的`keyword`模块来获取Python的关键词列表，然后再结合`collections`模块中的`Counter`函数进行词频统计。

以下是示例代码：

import keyword
from collections import Counter

# 获取Python关键词列表
keywords = keyword.kwlist

# 统计关键词出现次数
word_count = Counter(keywords)

# 输出结果
for word, count in word_count.items():
    print(f"{word}: {count}")

输出结果如下：

False: 1
None: 1
True: 1
and: 1
as: 1
assert: 1
async: 1
await: 1
break: 1
class: 1
continue: 1
def: 1
del: 1
elif: 1
else: 1
except: 1
finally: 1
for: 1
from: 1
global: 1
if: 1
import: 1
in: 1
is: 1
lambda: 1
nonlocal: 1
not: 1
or: 1
pass: 1
raise: 1
return: 1
try: 1
while: 1
with: 1
yield: 1
