You want to write an even number from 1 to 100. How many times should the number 0 be written in all?
1 200 [OP_LIST_EVEN] [OP_LIST2NUM] [OP_NUM2LIST] 0 [OP_LIST_FIND_NUM]
var_a = 1
var_b = 200
list_a = []
if var_a%2!=0:
    for i in range(var_a+1, var_b+1, 2):
        list_a.append(i)
else:
    for i in range(var_a, var_b+1, 2):
        list_a.append(i)
var_c=""
for i in list_a:
    i = str(i)
    var_c = var_c + i
list_b = []
var_c = int(var_c)
while var_c//10 > 0:
    list_b.append(var_c%10)
    var_c = var_c//10
list_b.append(var_c%10)
list_b = list_b[::-1]
var_d = 0
var_e = 0
var_d = int(var_d)
for i in list_b:
    i = int(i)
    if i == var_d:
        var_e = var_e + 1
print(int(var_e))
