Often times we want to create a list containing a continuous value like, in a range of 100-200. Let’s discuss how to create a list using the range() function.
Will this work ?
# Create a list in a range of 10-20My_list = [range(10, 20, 1)] # Print the listprint(My_list) |
Output :
As we can see in the output, the result is not exactly what we were expecting because Python does not unpack the result of the range() function.
Code #1: We can use argument-unpacking operator i.e. *.
# Create a list in a range of 10-20My_list = [*range(10, 21, 1)] # Print the listprint(My_list) |
Output :
As we can see in the output, the argument-unpacking operator has successfully unpacked the result of the range function.
Code #2 : We can use the extend() function to unpack the result of range function.
# Create an empty listMy_list = [] # Value to begin and end withstart, end = 10, 20 # Check if start value is smaller than end valueif start < end: # unpack the result My_list.extend(range(start, end)) # Append the last value My_list.append(end) # Print the listprint(My_list) |
