PyMemoryEditor 1.4.14

A Python library to edit and track memory of Windows processes (32 bits and 64 bits).

PyMemoryEditor

A Python library developed with ctypes to manipulate Windows processes (32 bits and 64 bits),
reading and writing values in the process memory.

Installing PyMemoryEditor:

pip3 install PyMemoryEditor

Basic Usage:

Import PyMemoryEditor and open a process using the OpenProcess class, passing a window title, process name
or PID as an argument. You can use the context manager to do this.

from PyMemoryEditor import OpenProcess

with OpenProcess(process_name = "example.exe") as process:
    # Do something...

After that, use the methods read_process_memory and write_process_memory to manipulate the process
memory, passing in the function call the memory address, data type and its size. See the example below:

from PyMemoryEditor import OpenProcess

title = "Window title of an example program"
address = 0x0005000C

with OpenProcess(window_title = title) as process:

    # Getting value from the process memory.
    value = process.read_process_memory(address, int, 4)

    # Writing to the process memory.
    process.write_process_memory(address, int, 4, value + 7)

Getting memory addresses by a target value:

You can look up a value in memory and get the address of all matches, like this:

for address process.search_by_value(int, 4, target_value):
    print("Found address:", address)

Choosing the comparison method used for scanning:

There are many options to scan the memory. Check all available options in ScanTypesEnum.

The default option is EXACT_VALUE, but you can change it at scan_type parameter:

for address process.search_by_value(int, 4, target_value, scan_type = ScanTypesEnum.BIGGER_THAN):
    print("Found address:", address)

Extra information from search_by_value method:

This method also has the progress_information parameter that returns a dictionary containing search progress information.

for address, info process.search_by_value(int, 4, target_value, progress_information = True):
    template = "Address: 0x{:<10X} | Progress: {:.1f}%"
    progress = info["progress"] * 100
    
    print(template.format(address, progress))
