for example:
list_1 = ["1,2,3"]
empty_list = []
print (list_1)
123
print (empty_list)
[]
sorry for my English 😩

In the continue Loop -
i = 0
while True:
i = i +1
if i == 2:
print("Skipping 2")
continue
if i == 5:
print("Breaking")
break
print(i)
print("Finished")
It shows the output being
"1
Skipping 2
3
4
Breaking
Finished"
Why are the last three lines not
"Breaking
5
Finished"
Where it shows print(i) after break?

public static void main (string[ ] args)
i have understood little bit that public means for whole method.
static?
void?
main is a method which creates a string array named args. why the name args?
please explain and correct if i am wrong?

Why this code runs?:
nums = [4, 5, 6]
msg = "Numbers: {} {}". format(nums[0], nums[1], nums[2])
print(msg)
Numbers:4, 5.
Byt the code:
nums = [4, 5, 6]
msg = "Numbers: {} {} {} {}". format(nums[0], nums[1], nums[2])
print(msg)
leading to error?
IndexError: tuple index our of range
