Η πιο αφαιρετική άσκηση μέχρι στιγμής.
Αισθάνθηκα λίγο χαμένος, απ'την άποψη οτι δυσκολευόμουν να ακολουθήσω τη συλλογιστική της επίλυσης γραμμικά. Δηλαδή δεν αντιλαμβάνομαι καλά τη σειρά ή την αιτία σειράς των βημάτων. Σα να μην έχει σαφή αρχή, μέση, τέλος, αλλά να ξεκινάμε το puzzle τοποθετώντας κομματάκια πάνω στο τραπέζι που δεν είναι εμφανές γιατί τα βάζουμε εκεί που τα βάζουμε και μόνο όταν αρχίζει και σχηματίζεται μπόλικο μέρος της εικόνας αντιλαμβάνομαι πως όντως ήταν σωστά. Ίσως και να μην ήπια αρκετό καφέ σήμερα και να φταίω εγώ. Θα συνεχίσω να την μελετώ πριν προχωρήσω ωστόσο.

Γι'άλλη μια φορά πάντως να'στε καλά για την υπερπολύτιμη προσφορά γνώσης!
Όταν καταφέρω να αρχίσω να εργάζομαι ως προγραμματιστής θα σας ανταποδώσω τη χάρη!

Καλησπέρα δάσκαλε, για πολλοστή φορά συγχαρητήρια και σε ευχαριστούμε για όλα! Σχολιάζω σε αυτό το βίντεο για να κάνω μια επισήμανση, ο κώδικας έχει δυο μικρά bug-άκια. Όταν επιλέξεις να συνεχίσεις να παίζεις (Do you want to play again(y-yes, n-no):), σε κάθε επανάληψη βγαίνουν ακριβώς τα ίδια φύλλα και για τον player και για το computer. Επιπλέον, για την περίπτωση που το χαρτί είναι άσος, στο πρόγραμμα είδαμε τις περιπτώσεις να είναι 1 ή 10, αντί για 1 ή 11.

Μετα απο τις ολιγοημερες διακοπες επιστρεψαμε στα βιντεο σας κυριε Ψουνη.
Το ξερω πως η λυση μου επιδεχεται εκλεπτυνσεις αλλα για χαρη χρονου, και γιατι βλεπω ολα τα βιντεο σας απο την σειρα ΠΛΗ αρκεστηκα σε αυτη τη λυση.
Αυτο που εκανα εγω οσον αφορα την αρχικοποιηση της τραπουλας ηταν να φτιαξω μια συναρτηση που στην ουσια μας επιστρεφει την τραπουλα απο την αρχη στην αρχη καθε νεου γυρου!
Βεβαια δεν ξερω αν αντιβαινει στην λογικη της ασκησης γιατι επρεπε να ειναι καθολικη μεταβλητη, αλλα ετσι το εκανα!

Καλημέρα! Αρχικά να σας ευχαριστήσω για την προσπάθεια σας και την γνώση που χαρίζετε. Δεύτερον να πω ότι είστε πολύ μεταδοτικός, ειδικά για εμένα που ήμουν άσχετος εντελώς, αν και καποιες φορές λογικά, ειδικά στον κώδικα δεν σας προλαβαίνω, αλλά πάλι ευτυχώς υπάρχει και το STOP & REPLAY.
Κάποιες φορές βέβαια ενώ σε εσάς τρέχει σε εμένα όχι αλλά το παλεύω. Γενικά δεν μπορώ να καταλάβω, ακόμη ελπίζω, ποιο μπαίνει που αλλά ελπίζω να το βρω στο τέλος. Γιατί το πάλεψα πολύ πριν δω την δική σας λύση, σε κάποια έφτασα κοντά αλλά σε κάποια άλλα ....Πάντως έτσι και έτσι είμαι σε πολύ καλύτερο επίπεδο από πριν και περιμένω πως και πως να τελειώσω την σειρά για να την ξαναδώ και να διορθώσω τα λάθη μου και να γεμίσω τα κενά μου. Ευχαριστώ και πάλι.
Τέλος να πω ότι στο παιχνίδι αυτό σας διέφυγε να αυξήσετε τον μετρητή rounds

Μπορείτε να μας πείτε πού μπορούμε να βρούμε παρόμοιες ασκήσεις όπου υλοποιούμαι μικρά παιχνίδια ή κάποιο άλλο πρόγραμμα; Επίσης, τις δικές σας εκφωνήσεις των ασκήσεων που τις ανεβάζετε;

μια μικρή τροποποίηση στην hand_value.Αν ο παίκτης ή ο υπολογιστής έχει στο χέρι του παραπάνω από εναν άσσο τοτε το παρακάτω προγραμμα θα του εμφανίζει ενα λίγο καλύτερο ενδεχόμενο επιλογών

Καλησπέρα κύριε Ψούνη. Είπα να προσθέσω και έλεγχο για πληκτρολόγηση σωστά του ναι ή όχι όπως φαίνεται στο τέλος .Αυτό που μου συμβαίνει συχνά είναι να μην αναγνωρίζει το brake και να μου το βγάζει υπογραμμισμένο γιατί να συμβαίνει αυτό;
Αυτό το το while εμπεριέχεται στο while true της main μετά το rounds και score.

Στο τελευταίο αρχείο που έχει ανέβει για την άσκηση αυτή, κρατάει τις ίδιες κάρτες σταθερά σε όλους τους γύρους. το deck στην σειρά 79 πρέπει να σβηστεί μόνο?

[asteriosalexiou]

Καλησπέρα κ. Ψούνη, θα μπορούσαμε σε κάθε input() να βάλουμε τις μεθόδους .lower() ή .upper() οπότε δεν θα είχαμε πρόβλημα αν ο χρήστης πληκτρολογεί με μικρά ή κεφαλαία. Επίσης, δεν αλλάζουμε το rounds, παραμένει πάντα 1. Τέλος, δεν αρχικοποιούμε το deck
