you can change the screen size by altering the values of width(600) and height(300)
ReplyDeletescreen = pygame.display.set_mode((600, 300))
ReplyDeletepygame.draw.circle(screen, (255, 0, 0), [300, 150], 35)
Note:
screen = pygame.display.set_mode((600, 300))
pygame.draw.circle(screen, (color of circle), [x, y coordinates], radius of circle)
clock.tick(5)

check if you have compatible version of python and pygame.
Deletepygame-1.9.2a0.win32-py3.2
python-3.2
Note:
mine is 32 bit. check your system configuration
Happy programming...
Anu
try and tell me if it works
Deletethanks
Anu
my python version is 3.7.3
Deletethen i installed pygame-1.9.2a0.win32-py3.2
still it is showing trace back error like
Traceback (most recent call last):
File "C:/PYTHON/pg.py", line 3, in
import pygame
ModuleNotFoundError: No module named 'pygame'
please solve my problem
You need compatible versions of python and pygame. ur pygame is 3.2 and python is 3.7. wont work.

Im getting this error...
check

Iam also getting error. and yes I have checked import sys line

IndentationError: unexpected indent
yours is an indentation error. not in import.
Deletescreen.fill((0,0,0)) should be in same indent as previous lines within the for loop.
Thankyou mam helped a lot on exams
ReplyDeletei need algorithm for that simulation program of elliptical orbit in pygame
