Question

python list 统计字母个数

比方说a=["abc","def","ghi"],我要统计字母个数，也就是9个，怎么解？
或者请教大神有没有方法把字母拆开，a=["abc"]变成a=["a","b","c"]?
thx

Answer 1

都是字母的话可以简单这样统计个数

a=["abc","def","ghi"]
count=0
for i in a:
count+=len(i)
print(count)

---9
要拆开，用list()函数就可以了。
a=["abc","def","ghi"]
b=[]
for i in a:
b.append(list(i))
print(b)

---[['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h', 'i']]

Answer 2

a=["abc","def","ghi"]
len(''.join(a))
