'''
if 语句用以检查条件:如果 条件为真(True),我们将运行一块语句(称作 if-block 或 if 块),
否则 我们将运行另一块语句(称作 else-block 或 else 块)。其中 else 从句是可选 的。
'''
# 设置变量
number = 23
# input() 函数来获取用户 的猜测数
guess = int(input('Enter an integer: ')) # int 将这个字符串转换成一个整数并将其储存在变量 guess 中
# if条件语句
if guess == number:
# 新块从这里开始
print('Congratulations, you guessed it. ')
print('(but you do ont win any prizes!)')
# 新块从这里结束
elif guess < number:
# 另一代码块
print('No,it is a little higher than that')
# 你可以在此做任何你希望在该代码块内进行的事情
else:
print('No,it is a little lower than that')
# 你必须通过猜测一个大于(>)设置数的数字来到达这里。
print('Done')
# 这最后一句将在
# if 语句执行完毕后执行
You can’t perform that action at this time.
