Word frequency statistics & sorting

# Word frequency statistics 
sent = "python is my favoriate language,you're so cute   ,someone like you ~~,do what shhhh"
# newest 
output = {k:sent.count(k) for k in set(sent)}# Get word frequency statistics quickly 
print(output)


output = {k:sent.count(k) for k in set(sent.split(" "))}# Get word frequency statistics quickly 
print(output)

chset = "abcdefghijklmnopqrstuvwxyz-' "
sent = sent.lower()# Lowercase letters 
for c in sent:
    if c not in chset:
        sent = sent.replace(c," ")

wd_lst = sent.split(" ")# Split by spaces 
wd_lst

dt = {}
for k in wd_lst:
    if k not in dt.keys():
        dt[k] = 0
    dt[k]+=1

wd_s = set(wd_lst)
dt1 = {}
for k in wd_s:
    dt1[k] = wd_lst.count(k)

According to the value It's worth it key Sort ：

a1 = sorted(word_freqs_c.items(),key = lambda x:x[1],reverse = True)
