How to get value from address in Python

To get a value from a memory address in Python, you can use the ctypes
module. The ctypes
module allows you to access C library functions and data types from Python. Here’s an example of how to use ctypes
to get the value at a specific memory address:
import ctypes
# define a variable of the appropriate data type for the memory address you want to read
value = ctypes.c_int()
# get the memory address you want to read
address = 0x7fff5fbff618
# read the value from the memory address
ctypes.memmove(ctypes.addressof(value), address, ctypes.sizeof(value))
# print the value
print(value.value)
In this example, we define a ctypes.c_int()
variable to match the data type stored at the memory address we want to read. We then use the memmove()
method to copy the data from the memory address to our value
variable. Finally, we print the value of our value
variable.
Note that this approach is generally not recommended unless you know exactly what you’re doing, as it can lead to memory errors and crashes if used improperly.
