Python基础入门

# a = str(input("请您输入数字a："))  # 输入str型变量a
# b = int(input("请您输入数字b："))  # 输入int型变量b
# a = int(a)  # 强转
# if(a == b):
#     print("a=b")
# elif (a < b):
#     print('a<b')
# else:
#     print("a>b")


# for i in range(1, 5):
#     for j in range(1, 3):
#         print(i)


# a = []  # 新建一个数组
# n = int(input())
# for i in range(n):  # =for i in range(0, n):
#     a.append(int(input()))
# for i in range(n):
#     print(a[i])

# b = [6, 7, 8, 9]
# c = [1, 2, 3]
# b.extend(c)  # 将c数组‘接到’b数组之后
# print(b)
# b.sort()  # 排序
# print(b)
