result=[x?for?x?in?range(2,101)?if?isprime(x)]

解釋， 還是建議先定義判斷函數 ，命名為 pythonic 風格 isprime(), 然后用 列表推導式 生成結果吧， 或者將列表表達式包裝為函數？

def?prime_list(start,end):
????def?isprime(n):
????????if?not?isinstance(n,int)?or?n<=1:
????????????return?False
????????for?i?in?range(2,int(math.sqrt(n)+1)):
????????????if?n?%?i?==0:
????????????????return?False
????????return?True
????return?[x?for?x?in?range(start,end+1)?if?isprime(x)]
????
result?=?prime_list(2,100)

基本就這樣吧

#?coding:?utf-8

def?isPrime(number):
????for?x?in?range(2,number/2):
????????if(number?%?x?==?0):
????????????return?False
????return?True

a?=?[]
for?x?in?range(2,101):
????if(isPrime(x)):
????????a.append(x)

print?a
