If method A calls B, and B calls C, and then an error is raised in function C, where can it potentially be caught (A, B, C, or all of the above)?
Answer
You could write a short code and try it yourself. Something like this:
def func1(a): #will call func2
print("in first func #1")
x=a^2
func2(x)
print("in first func #2")
def func2(b): #will call func3
print("in second func #1")
func3(b*2)
print("in second func #2")
def func3(c): #function with error
print("in third func #1")
print(c+ "str") #can't use + operator on str and int type
print("in third func #2")
a=5
func1(a)
You’ll end up with this error:
in first func #1
in second func #1
in third func #1
Traceback (most recent call last):
File "--", line 15, in <module>
func1(a)
File "--", line 4, in func1
func2(x)
File "--", line 8, in func2
func3(b*2)
File "--", line 12, in func3
print(c+ "str") #can't use + operator on str and int type
TypeError: unsupported operand type(s) for +: 'int' and 'str'
It can be caught in func3
