This lecture explains iteration in simple programs like guess-and-check, binaries, and fractions in Python. Loops can iterate over any sequence of values including a range for numbers or a string. Guess-and-check provides a simple algorithm for solving problems. When the set of potential solutions is enumerable, exhaustive enumeration is guaranteed to work (eventually). Binary numbers help us understand how the machine works. Converting to binary will help us understand how decimal numbers are stored

Now ending day 2 of python

[@andiuptown1711]

Where are you now?

[@ashutosh77577]

Aur bhai kahan pe padh rhe ho aap ?

[@harshshukla12]

​@@andiuptown1711 I actually dropped it in between, because on Scaler, these courses are available with great practice problem too. And progress traking and certificate for free.

[@shamrockshane]

These youtryit's and at-home exercises are TOO HARD

[@andiuptown1711]

No they’re not 😂

[@blackmvs]

They are easy tf do you mean🤧
