试图学习while循环会遇到意外的缩进和语法错误？ （蟒蛇）

Question

The following code gives me unexpected indent I have tried many variations but I keep getting these errors or syntax errors

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

The while loop needs a contained code block:

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")
