How can i judge 1st string position is correct number

[newbieAuggie2019]

May i ask. what function i can use to make me confirm my string position number one number if i get 1, i will get ok else i will get fail.

Hi!

Maybe this can give you some ideas:

mystring = "11000000000000000000000000000000"

for character in mystring:
    if character  == '1':
        print(f"O.K., the character '{character}' in my string is '1'.")
    else:
        print(f"Fail, the character '{character}' in my string is not '1'.")

and that produces the following output:

Output:
O.K., the character '1' in my string is '1'.
O.K., the character '1' in my string is '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.
Fail, the character '0' in my string is not '1'.

Hi again!

If you are looking for a certain position in the string, this may give you some ideas (although it's not very good code, but I think it's easier for newbies):

mystring = "abcdefghijk"

for positions in range(len(mystring)):
    if mystring[positions]  == 'g':
        print(f"O.K., the character '{mystring[positions]}' in my string is 'g'.")
    else:
        print(f"Fail, the character '{mystring[positions]}' in my string is not 'g'.")

that produces the following output:

Output:
Fail, the character 'a' in my string is not 'g'.
Fail, the character 'b' in my string is not 'g'.
Fail, the character 'c' in my string is not 'g'.
Fail, the character 'd' in my string is not 'g'.
Fail, the character 'e' in my string is not 'g'.
Fail, the character 'f' in my string is not 'g'.
O.K., the character 'g' in my string is 'g'.
Fail, the character 'h' in my string is not 'g'.
Fail, the character 'i' in my string is not 'g'.
Fail, the character 'j' in my string is not 'g'.
Fail, the character 'k' in my string is not 'g'.
>>> 

So you can check a character in a certain position, for instance:

Output:
>>> mystring = "abcdefghijk"
>>> mystring[0]
'a'
>>> mystring[3]
'd'
>>> mystring[5]
'f'
>>> mystring[8]
'i'
>>> mystring[10]
'k'
>>> 

I hope it helps.

All the best,
