## Solution
A quick google search revealed that `.schematic` files are in the `NBT` file format.
From Minecraft Wiki
Open the file using `NBTExplorer`.
NBTExplorer GUI
At the start I thought the `dispenser` will be one of the `TileEntities` so I tried to find it using the following python code:
```python
from nbt import nbt
nbtfile = nbt.NBTFile("Ricardo3s_60AP_100C_200SB.schematic",'rb')
for tileentities in nbtfile['TileEntities']:
try:
for item in tileentities['Items']:
print(item)
except:
print(tileentities)
```
As it turns out, `TileEntities` only contain either `minecraft:tnt` item or a Minecraft `Comparator`.
Python output
I then proceeded to search up on Minecraft dispenser to find out what exactly it is since it is not in `TileEntities`.
From Minecraft Wiki once again
It seems like a `Dispenser` is a **block**. I then edited the python script to print out all the blocks.
```python
from nbt import nbt
nbtfile = nbt.NBTFile("Ricardo3s_60AP_100C_200SB.schematic",'rb')
print(nbtfile['Blocks'])
```
The output is as follows:
Python output
The output is an array of numbers which suggests that every block is stored as a unique number that determines which block type it is. Previously from the Minecraft wiki page, we can also see the number 23 under the dispenser's **Numeric ID**. Now we just need to count the number of dispensers with the following code:
```python
from nbt import nbt
nbtfile = nbt.NBTFile("Ricardo3s_60AP_100C_200SB.schematic",'rb')
# Count number of blocks with 23 as Numeric ID
print(len([i for i in nbtfile['Blocks'] if i == 23]))
```
Flag: `bucket{2238}`
