We want to combine the two modified data frames into one data using the merge method. The shape of each data frame is 16598 rows × 6 columns. The result was expected to be (16598 rows × 6 columns). However, the combined result was (16602 rows × 7 columns), and the number of rows increased by four. The code I used is as follows.

I have regular expression to find car registration with and without spaces.

I am using assembler for the ARM7TDMI (ARMv4T architecture). I'm using the Thumb mode because the ROM has a 16-bit bus (GBA). I want to sign-extend a 32-bit register to get another register with all bits set to a copy of bit 31 of the source register. The register to sign-extend is a high register, in particular R9.

I'm currently using this:

I have a pd Dataframe and some values are nan.

What I would like to do is assign nan values to all the elements of a row (excluding the element of the first column) if that row has one nan value.

For example, given the following dataframe:

I have a dataset with missing data after year 2015, so I need to remove NaN values and entries after 2015(2016-2020). I can remove NaN values using this code

I'm in the Lua console of the Bizhawk emulator. I want to edit Ram of a GBA game.

I have a directory with a Lua file and another folder, that has a text file in it. I managed to read text from it by using the absolute path but I want to make it work with the relative path.

I tried to use arg[0] to get the path of the file but it's nil. And this outputs me 'ain': debug.getinfo(1,"S").source:sub(2)

So i have a dataframe, df:

I am trying to find a way to insert a string ' .sh' into a particular line in a text file using sed. The problem i have is that i only want to insert the string if a previous regex matches, it also has to support a variable number of lines between the 'name' and 'extension' tag and to be idempotent, so i can run it multiple times with only a single insertion of ' .sh' for the 'extension' tagged space separated list.

Here is a small snippet of the text file:-

I'm trying to create a matching GBA disassembly using devkitpro, and I'm having trouble with the THUMB instruction LDR R1, =0x3FF.

I want it to place 0x3FF in the literal pool and generate a PC-relative address, which is what the assembled version does, however it insists on creating a MOVW 32-bit instruction instead.

I've tried using the length specifier LDR.N to force it to generate a 16-bit instruction, however this appears to have made no difference at all.

While I could just use the PC-relative address directly, since this is in the middle of the literal pool it would cause me to have to delete a large amount of the pool and implement the loads in the same way, which would be very messy, so this is only a last resort. If anyone knows some way I could force this instruction to generate a PC-relative address that would be very helpful. Thanks!
