bookFor Loop

We use loops if we want to repeat any action n-times.


              
1234

            
prices = [100, 458, 231, 378]

for i in prices:
  print(i, end = '')
copy

              
12345

            
# Decreasing prices by 1
prices = [3, 5, 6, 2, 7, 8]

for i in prices:
  print(i, end = ' ')
copy

end = ' ' means that the result will be written in one row (not column).
