初学python 想到的方法👀 能解不知道还有没有更好的
str = "bccdaAB"
data ={}
for i in str:
if i.isupper():
data[i] = data.get(i,0) + 1
elif i.islower():
data[i] = data.get(i,0) + 1
keys = sorted([ord(key) for key in data.keys()])
for key in keys:
if key+32 in keys:
keys.remove(key+32)
keys.insert(keys.index(key)+1,key+32)
result = {}
for i in keys:
result[chr(i)] = data[chr(i)]
print(result)
