From ?scale_x_continuous about the expand-argument:
Vector of range expansion constants used to add some padding around

How to do parallel programming in Python?
...ugh it only works with a small subset of Python:
from numba import njit, prange
@njit(parallel=True)
def prange_test(A):
s = 0
# Without "parallel=True" in the jit-decorator

But here comes the difference:
If const int temp is a modifiable ID instead of a one-time-programmable serial number and is NOT declared volatile, a cached value...

Checking whether a variable is an integer or not [duplicate]

Example (to do something every xth time in a for loop):
for index in range(y):

Edit:
You can always convert to a float before calling this method. The three possibilities:
>>> float(5).is_integer()
