Question

我正在尝试在'words.txt'文件中打印所有字母的计数和小数频率，不包括\ n字符。我已经编写了以下代码段

FILENAME = 'words.txt'

fvar = open(FILENAME, 'r')  # open file for reading

bigline = fvar.read() # read ENTIRE file into single string
print("Number of characters is: %d" % len(bigline))

length_without_newlines = len(bigline) - bigline.count('\n')


ref_string = 'abcdefghijklmnopqrstuvwxyz'

num_l = 0

for x in bigline:
    if x in ref_string:
        num_l += 1
print('Count of letter',x, 'is: ', num_l)
frac_freq  =  float(num_l)/float(length_without_newlines)

#This isn't working properly

是否可以遍历ref_string并打印每个字母的计数和小数频率（换行符除外）；也就是说，将特定字母的计数除以文件中字母的总数，而不计算换行符？由于我是python的新手，所以如果有人可以更新此函数的代码，那就太好了。

希望此示例有所帮助：

from collections import Counter

counter = Counter('line')
total = sum(counter.values())
for letter, count in counter.items():
    print(f'Count of letter {letter} is: {count}')
    frac_freq = float(count)/float(total)

word.txt文件中所有字母的计数和小数频率
