Is there a simple way to delete a list element by value?

Question

a=[1,2,3,4] b=a.index(6) del a[b] print aThe above shows the following error:<!-- language: lang-none --> Traceback (most recent call last): File "D:\\zjm_code\\a.py", line 6, in <module> b=a.index(6) ValueError: list.index(x): x not in listSo I have to do this: a=[1,2,3,4] try: b=a.index(6) del a[b] except: pass print aBut is there not a simpler way to do this?

Answer 1

a = [1, 2, 3, 4] #define a list

b = a.index(6) # what element in the list has the value of 6? Answer: none

Simple way:

a.remove[6]
