[Python] Python string[] and float weird behavior? [closed]

I am using Python to communicate between a RaspberryPi and an ESP32, so I send strings back and forth and "decode" to get the data I need.

So for my test string I have: input_string = "2;068;060;076;030;000;000;000;000;000;000;000;000;000;000;000;000;000;000"

I'm trying to get the "068" characters (which should be [2:4], right?) to convert them into a float with:

float(input_string[2:4])


Which only yields "6.0" as an awswer.

I then tried a bunch of different values and print them off to understand what was going on:

print(input_string)
print(input_string[2:4])
print(input_string[2:5])
print(float(input_string[2:5]))


And this returns:

"2;068;060;076;030;..."
"06"
"068;"
"68.0"


I mean, why does [2:4] return "06" and [2:5] return "068;"? Also, since "068;" has a non-number character, it should return an error when used in "float()", and it just doesn't.

Am I missing something too obvious?

Edit: fixed the output part in the correct identation
