我想知道是否有人可以帮助我。
如何获取此代码,以仅将文本文件中字母的频率记录到字典中(不计算空格,行,数字等)?
另外,如何将每个字母除以总字母,以报告文件中每个字母的频率百分比?
这是我目前拥有的:
def linguisticCalc():
"""
Asks user to input a VALID filename. File must be a text file. IF valid, returns the frequency of ONLY letters in file.
"""
filename = input("Please type your VALID filename")
if os.path.exists(filename) == True:
with open(filename, 'r') as f:
f_content = f.read()
freq = {}
for i in f_content:
if i in freq:
freq[i] += 1
else:
freq[i] = 1
print(str(freq))
else:
print("This filename is NOT valid. Use the getValidFilename function to test inputs.")

可以帮助您确定所讨论字符是否为字母的东西是
$(function() {
function makeModal(cnt, t) {
var dlg = $("<div>", {
title: t
}).html(cnt);
dlg.dialog({
classes: {
"ui-dialog": "clear",
"ui-dialog-titlebar": "pale",
"ui-dialog-content": "clear",
"ui-dialog-buttonpane": "no-show",
"ui-dialog-buttonset": "no-show"
},
resizable: false,
modal: true,
width: 550,
height: 722,
show: {
effect: "fade",
duration: 300
},
close: function(e, ui) {
$(this).dialog("destroy");
}
});
}
$(".thumb").click(function(e) {
e.preventDefault();
var i = $(this).find("img");
makeModal(i.prop("outerHTML"), i.attr("alt"));
})
});

您可以使用它来计数字符串中的每个字母:
Counter('Articles containing potentially dated statements from 2011')
它给出以下输出,这对于计数字符串中的字符很有用:
计数器({'A':1, 'r':2 't':8 '我':4, 'c':2 'l':3, 'e':5 's':3, '':6, 'o':3, 'n':5 'a':4 'g':1 'p':1, 'y':1 'd':2 'm':2 'f':1 '2':1 '0':1 '1':2})
