To print traingle pattern by taking input from user, first we have to store the user input in a variable.
Example: If user gives input as 5, the number of rows and columns in the traingle must be 5.
Code :
user_input = input("enter no of lines")
for x in range(int(user_input)):
for y in range(int(user_input)) :
if y <= x :
print("* \t" ,end="")
print("")
The above python code will give the output as shown below:
enter no of lines
Let us keep the user input as 5.
The output terminal will give you the output as below:
enter no of lines 5
