python計算100以內的素數

# 方法一
print("， ".join("%s" % x for x in range(2,101) if not [y for y in range(2,x) if x % y ==0]))

# 方法二
# list = []
# i = 2
# for i in range(2, 100):
#     j = 2
#     for j in range(2,i):
#         if(i%j==0):
#             break
#     else:
#         list.append(i)
#
# print(list)

# 方法三
# i = 2
# c = []
# while i <= 100:
#     j = 2
#     while j <= i:
#         if i % j == 0:
#             if i == j:
#                 c.append(i)
#             break
#         j += 1
#     i += 1
# print(c)
