Access strings which is inside the list : Python list has ['12:30','12:45'] and I want to access the '12:30' for the first iteration and the second iteration I should get '12:45'

my_list=['12:30','12:45']
for each_value in my_list:
    print(each_value[0])


my_list=['12:30','12:45']
for each_value in my_list:
    print(each_value[0])

The expected result is '12:30' but the acutal output is '1'
