from a python code to matlab code

how can I convert the following code to matlab code?

cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]

print("Cuts under 30: " "{}".format(cuts_under_30))

Try this:

clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables. Or clearvars if you want.
%workspace;  % Make sure the workspace panel is showing.
format short g;
format compact;
fontSize = 20;
hairstyles = {'bouffant', 'pixie', 'dreadlocks', 'crew', 'bowl', 'bob', 'mohawk', 'flattop'};
prices = [30, 25, 40, 20, 20, 35, 50, 35];
last_week = [2, 3, 5, 8, 4, 4, 6, 2]; 
%my code
total_price = 0; 
for price = 1:length(prices)
    total_price = total_price + prices(price);
end
disp(total_price);

   255

average_price = total_price/numel(prices);
fprintf('Average Hair Cut Price is: %.3f\n', average_price);

Average Hair Cut Price is: 31.875

%problem #5
new_prices = prices()-5;
disp(new_prices);

    25    20    35    15    15    30    45    30

%fprintf('The new prices are: %.2f\n', new_prices);
%Revenue
total_revenue = 0; 
total_revenue = sum(prices.*last_week);
fprintf('Total Revenue is: %.f\n', total_revenue);

Total Revenue is: 1085

%average revenue
average_revenue = total_revenue/7; 
fprintf('The average revenue is: %.f\n', average_revenue)

The average revenue is: 155

% cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]
indexes = new_prices < 30;
cuts_under_30 = hairstyles(indexes)

cuts_under_30 = 1×4 cell array
    {'bouffant'}    {'pixie'}    {'crew'}    {'bowl'}

prices_under_30 = new_prices(indexes)

prices_under_30 = 1×4

25 20 15 15

fprintf('Cuts under 30 :\n')

Cuts under 30 :

for k = 1 : length(prices_under_30)
    fprintf('%s costs $%.2f\n', cuts_under_30{k}, prices_under_30(k));
end

bouffant costs $25.00
pixie costs $20.00
crew costs $15.00
bowl costs $15.00

fprintf('\n')

Thank you so much...was trying to figure that out for a while...

% cuts_under_30 = [hairstyles[i] for i in range(len(hairstyles)) if new_prices[i] < 30]
cuts_under_30 = hairstyles(new_prices < 30);

[Image Analyst]

Then, to print to the command window:

fprintf("Cuts under 30 :\n")
fprintf('%.2f ', cuts_under_30);
fprintf('\n')

[Chunru]

Or simply remove the semicolon at the end of the statement.

It didn't work....Here is the whole code I am working on from Python...

hairstyles = ["bouffant", "pixie", "dreadlocks", "crew", "bowl", "bob", "mohawk", "flattop"];

prices = [30, 25, 40, 20, 20, 35, 50, 35];

last_week = [2, 3, 5, 8, 4, 4, 6, 2]; 

%my code
total_price = 0; 
for price = 1:length(prices)
    total_price = total_price + prices(price);
end
disp(total_price);

average_price = total_price/numel(prices);
fprintf("Average Hair Cut Price is: %.3f\n", average_price);

%problem #5
new_prices = prices()-5;
disp(new_prices);
%fprintf("The new prices are: %.2f\n", new_prices);

%Revenue
total_revenue = 0; 
total_revenue = sum(prices.*last_week);
fprintf("Total Revenue is: %.f\n", total_revenue);

%average revenue
average_revenue = total_revenue/7; 
fprintf("The average revenue is: %.f\n", average_revenue)

%cuts under 30 
%cuts_under_30 = ;
% for cuts_under_30 = 1:numel(hairstyles)
%     i = hairstyles(cuts_under_30);
%     if new_prices < 30
% end
% disp(cuts_under_30)
fprintf("Cuts under 30 :\n")
fprintf('%.2f ', cuts_under_30);
fprintf('\n')

hairstyles = ["bouffant", "pixie", "dreadlocks", "crew", "bowl", "bob", "mohawk", "flattop"];
prices = [30, 25, 40, 20, 20, 35, 50, 35];
last_week = [2, 3, 5, 8, 4, 4, 6, 2]; 
total_price = sum(prices)

total_price = 255

average_price = mean(prices)

average_price = 31.8750

new_prices = prices()-5;
total_revenue = sum(prices.*last_week)

total_revenue = 1085

average_revenue = total_revenue/7

average_revenue = 155

cuts_under_30 = last_week(new_prices < 30)  % the number of haircuts under $30

cuts_under_30 = 1×4

2 3 8 4

hairstyles (new_prices < 30)    % the styles of haircuts under $30

ans = 1×4 string array
    "bouffant"    "pixie"    "crew"    "bowl"

new_prices(new_prices < 30) 

ans = 1×4

25 20 15 15
