一步一步调出来的，很笨的方法

s = input()
s +=' '
c = ''
res = []
tmp = 0
for i in range(len(s)):
    if s[i]=='"' and s[i+1]!=' ':
        idx = s[i+1:].index('"')
        tmp = i+1+idx
        c = c +s[i+1:i+1+idx]
        res.append(c)
        c = ''
    elif i>=tmp and s[i]!='"':
        if s[i]!=' ':
            c = c + s[i]
        elif c!='' :
            res.append(c)
            c = ''
# res.append(c)
print(len(res))
for i in res:
    print(i)
