python path code example

Example 1: python commands

simple python commands

print("your text here")

-----------------------------

name = input("what is your name")
print("nice to meet you " + name)

-----------------------------

A = int(input("give me the first num "))
B = int(input("give me the second num "))
f = A + B
print(f)

Example 2: python pathfinding module

#You can install this module with  >>pip install pathfinding

#You first need to import the module
from pathfinding.core.diagonal_movement import DiagonalMovement
from pathfinding.core.grid import Grid
from pathfinding.finder.a_star import AStarFinder

#Then, create a grid. The 0 are obstacles.
matrix = [
  [1, 1, 1],
  [1, 0, 1],
  [1, 1, 1]
]
grid = Grid(matrix=matrix)

#You need now to set the start and the end.
start = grid.node(0, 0)
end = grid.node(2, 2)

#This line allow your program to move with diagonal movements.
finder = AStarFinder(diagonal_movement=DiagonalMovement.always) 

#Now you can run find_path.
path, runs = finder.find_path(start, end, grid)

print('operations:', runs, 'path length:', len(path))
print(grid.grid_str(path=path, start=start, end=end))
#If you want the list of instructions, print(path)

Example 3: add python to path windows 10

To add Python to the Windows Path, follow these steps:

1. Start the Run box and enter sysdm.cpl
2. In the System Properties window go to the Advanced tab and 
   click the Environment Variables button
3. In the System variable window, find the Path variable and 
   click Edit
4. Position your cursor at the end of the Variable value line 
   and add the path to the python.exe file, preceeded with 
   the semicolon character (;)

Example 4: python path to python executable

>>> import sys
>>> print(sys.executable)
C:\path\to\python.exe

Example 5: edit path variable using python

app_path = os.path.join(root_path, 'other', 'dir', 'to', 'app')
os.environ["PATH"] += os.pathsep + app_path

Example 6: add python to path

# On linux
$ which python; # Get Path of the executable
$ export PATH=$PATH:{PATH_PYTHON}; # but it isn't continue
# ----------------------
$ which python; # Get Path of the executable
export PATH=$PATH:{PATH_PYTHON}; # add in your ~/.bashrc or your ~/.zshrc
