python - 尝试学习 while 循环出现意外缩进和语法错误？ (Python)

Question

下面的代码给了我意外的缩进，我尝试了很多变体，但我不断收到这些错误或语法错误

while True:
try:
    a=int(input("Please enter a number to be counted down to: "))
    b=(a-1)
    for count in range (100,b,-1):
        print (count)
        break
except:
print ("wohoo")

Answer 1

while 循环需要一个包含的代码块:

while True:    
    try:
        a = int(input("Please enter a number to be counted down to: "))
        b = (a-1)

        for count in range(100, b, -1):
            print(count)

    except:
        print ("wohoo")
