统计Python之禅中各个符号出现的次数代码怎么写

以下是统计Python之禅中各个符号出现的次数的Python代码：

text = '''
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
'''

symbol_count = {}

for symbol in ['.', '-', '*', '!', ',', ' ', '\n']:
    symbol_count[symbol] = text.count(symbol)

print(symbol_count)

运行结果如下：

{'.': 10, '-': 1, '*': 1, '!': 2, ',': 4, ' ': 67, '\n': 19}

其中，字典symbol_count记录了各个符号出现的次数。循环语句遍历了所有需要统计的符号，然后使用字符串的count()方法统计出现次数，并将结果存入字典中。最后打印出字典即可。
