In this shot, we will discuss how to generate a left arrow pattern using stars in Python.
Different patterns can be generated using Python, once we have a strong grip over the concepts involving loops. Here we will use simple for loops to generate a left arrow pattern using stars.
To do this, we will use 3 for loops: one for the upper half, one for the middle, and the last for the lower half.
Let’s have a look at the code.
# Number of Rowsn=8# Upper Partfor i in range((n - 1) // 2, 0, -1):for j in range(i):print(" ", end = " ")print("*")# Middle Partfor i in range(n):print("*", end = " ")print()# Lower Partfor i in range(1, ((n - 1) // 2) + 1):for j in range(i):print(" ", end = " ")print("*")print()
Line 2: We take the input for the number of rows.
Lines 5-8: We create a for loop to generate the upper portion of the arrow.
Lines 11-13: We create another for loop to generate the middle portion of the arrow.
Lines 16-20: We create a for loop to generate the lower portion of the arrow.
The
endstatement is used to stay on the same line, and theprint()statement is used to move to the next line.
