Find the error, assume data is a string and all variables have been declared.
for ch in data:
if ch.isupper:
num_upper = num_upper + 1
if ch.islower:
num_lower = num_lower + 1
if ch.isdigit:
num_digits = num_digits + 1
if ch.isspace:
num_space = num_space + 1
Find the Error:
date_string = input('Enter a date in the format mm/dd/yyyy: ')
date_list = date_string.split('-')
month_num = int(date_list[0])
day = date_list[1]
year = date_list[2]
month_name = month_list[month_num - 1]
long_date = month_name + ' ' + day + ', ' + year
print(long_date)
Find the Error:
full_name = input ('Enter your full name: ')
name = split(full_name)
for string in name:
print(string[0].upper(), sep='', end='')
print('.', sep=' ', end='')

- I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency. To elaborate,…arrow_forwardI want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation.

- Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4.
