当我运行try-and-except时，有没有一种方法可以消除语法错误

Question

while True:
try:
a = float(input("Enter a number for how long the break between words should be:")
except ValueError:
print("YOu haven't entered a number")

1. 在我执行它之后：

   File "main.py", line 7
   except ValueError:
   ^
   SyntaxError: invalid syntax
   

2. 为什么会出现此错误？

Answer 1

此行末尾缺少一个右括号：

a = float(input("Enter a number for how long the break between words should be:")

Answer 2

您在第3行缺少右括号，您的代码应该是：

while True:
try:
a = float(input("Enter a number for how long the break between words should be:"))
except ValueError:
print("You haven't entered a number")
