## Challenging aspects
### Challenging aspects in above code
1. **Integration with Pandas**: Extending `pd.DataFrame` requires deep understanding of its internal mechanisms such as indexing methods (`loc`, `iloc`), handling missing data (`NaN` values), performance optimizations (vectorized operations), and ensuring compatibility with existing functionalities.
2. **Custom Data Types**: Incorporating additional data types specific to Conary’s ecosystem (e.g., `Version`, `VersionRange`) requires implementing custom serialization/deserialization methods (`__setitem__`, `__getitem__`, etc.), type checking within dataframe operations (like arithmetic operations), and ensuring they integrate seamlessly with pandas' type inference system.
3. **Backward Compatibility**: Ensuring that new features do not break existing functionality or introduce regressions is critical when extending widely-used libraries like pandas.
### Extension
1. **Advanced Indexing**: Implement advanced indexing capabilities that can handle complex queries involving custom data types such as ranges within `VersionRange`.
2. **Performance Optimization**: Optimize operations involving custom data types to ensure they do not degrade performance significantly compared to native pandas types.
3. **Custom Aggregations**: Implement custom aggregation functions that can operate on these new data types efficiently.
## Exercise
### Full exercise here
**Objective**: Extend `pd.DataFrame` by creating a subclass called `ConaryDataFrame` that supports additional data types specific to Conary’s ecosystem (`Version`, `VersionRange`). Ensure compatibility with existing pandas functionalities while adding new features specific to these types.
#### Requirements:
1. **Custom Data Types**:
- Define custom classes `Version` and `VersionRange`.
- Implement necessary methods for these classes including comparison operators (`__lt__`, `__le__`, etc.), serialization/deserialization methods (`__setitem__`, `__getitem__`), and any other necessary methods.
2. **DataFrame Subclass**:
- Create a subclass `ConaryDataFrame` extending `pd.DataFrame`.
- Override necessary methods (`__getitem__`, `__setitem__`, etc.) to support custom data types.
- Ensure compatibility with pandas indexing methods (`loc`, `iloc`).
3. **Advanced Indexing**:
- Implement advanced indexing capabilities that allow querying using `Version` and `VersionRange`.
- Example usage:
python
df = ConaryDataFrame({
'versions': [Version('1.0'), Version('1.1'), Version('2.0')],
'features': ['feature1', 'feature2', 'feature3']
})
result = df[df['versions'].between(Version('1.0'), Version('1.5'))]
4. **Performance Optimization**:
- Optimize operations involving custom data types ensuring they perform comparably to native pandas types.
5. **Custom Aggregations**:
- Implement custom aggregation functions that can operate on these new data types efficiently.
### Solution
python
import pandas as pd
class Version:
def __init__(self, version_str):
self.version_str = version_str
def __lt__(self, other):
return self.version_str.split('.') > other.version_str.split('.')
def __le__(self, other):
return self.version_str.split('.') >= other.version_str.split('.')
def __eq__(self, other):
return self.version_str == other.version_str
def __str__(self):
return self.version_str
def __repr__(self):
return f"Version('{self.version_str}')"
class VersionRange:
def __init__(self, start_version, end_version):
self.start_version = start_version
self.end_version = end_version
def contains(self, version):
return self.start_version <= version <= self.end_version
class ConaryDataFrame(pd.DataFrame):
@property
def _constructor(self):
return ConaryDataFrame
@property
def _constructor_sliced(self):
return pd.Series
def between(self, left=None, right=None):
mask = pd.Series([False] * len(self))
if left is not None:
mask |= self >= left
if right is not None:
mask |= self <= right
return self[mask]
# Usage Example:
df = ConaryDataFrame({
'versions': [Version('1.0'), Version('1.1'), Version('2.0')],
})
print(df[df['versions'].between(Version('1.0'), Version('1.5'))])
### Follow-up exercise
1. **Serialization/Deserialization**:
- Modify your solution so that instances of `ConaryDataFrame` can be saved to disk using CSV format while preserving custom data types.
2. **Custom Aggregations**:
- Implement custom aggregation functions such as finding all unique versions within certain ranges.
### Solution
python
import csv
class ConaryDataFrame(pd.DataFrame):
@property
def _constructor(self):
return ConaryDataFrame
@property
def _constructor_sliced(self):
return pd.Series
def between(self, left=None, right=None):
mask = pd.Series([False] * len(self))
if left is not None:
mask |= self >= left
if right is not None:
mask |= self <= right
return self[mask]
def to_csv(self, path_or_buf=None, sep=',', na_rep='', float_format=None,
columns=None, header=True, index=True,
index_label=None,
mode='w', encoding=None,
compression='infer', quoting=csv.QUOTE_MINIMAL,
quotechar='"', line_terminator='n',
chunksize=None):
if path_or_buf is None:
path_or_buf = sys.stdout
def serialize_version(v):
if isinstance(v, Version):
return str(v)
elif isinstance(v.columns[i], VersionRange):
return f"{v.start_version}-{v.end_version}"
else:
return v
csv_kwargs = {
"sep": sep,
"na_rep": na_rep,
"float_format": float_format,

"header": header,
"index": index,
"index_label": index_label,
"mode": mode,
"encoding": encoding,
"compression": compression,
"quoting": quoting,
"quotechar": quotechar,
"line_terminator": line_terminator,
"chunksize": chunksize,
}
if columns is not None:
csv_kwargs["usecols"] = columns
if index_label is not None and header == True:
csv_kwargs["header"] = [index_label] + (columns if columns else [])
writer = csv.writer(path_or_buf)
if header == True:
writer.writerow(csv_kwargs.get("header"))
for row in self.itertuples(index=index):
serialized_row = [serialize_version(item) for item in row]
writer.writerow(serialized_row)
# Usage Example:
df = ConaryDataFrame({
'versions': [Version('1.0'), Version('1.1'), Version('2.0')],
})
df.to_csv("output.csv")
# Custom Aggregation Function Example:
def unique_versions_in_range(df_col_series, range_obj):
unique_versions = set()
for version in df_col_series:
if range_obj.contains(version):
unique_versions.add(version)
return unique_versions
# Usage Example:
version_range = VersionRange(Version('1.0'), Version('2.0'))
print(unique_versions_in_range(df['versions'], version_range))
This exercise requires students not only to extend functionality but also consider serialization issues specific to their new custom data types while ensuring performance remains optimal.
*** Excerpt ***
This study demonstrates that intracellular Ca2+ signaling plays an important role in maintaining CFTR-dependent Cl− secretion by HCO3−/Cl− exchanger NBCe1-A activity via two mechanisms; first by controlling NBCe1-A protein abundance at cell surface through regulation of its internalization; secondly by modulating NBCe1-A activity via phosphorylation/dephosphorylation events at specific serine residues (Figures S7–S9). The present study identifies CaMKII as an important Ca2+ sensor regulating NBCe1-A activity via phosphorylation at S1019 residue located within cytoplasmic loop between TM8 and CTX domains; this residue appears critical because mutation at this site completely abolished CaMKII-dependent regulation of NBCe1-A activity (Figure S9). However we cannot exclude possibility that other phosphorylation sites might also be involved in regulation by CaMKII because many ion transporters including CFTR itself are regulated by multiple phosphorylation sites [54]. Our findings reveal an unexpected role of intracellular Ca2+ signaling during airway surface liquid secretion where it contributes significantly by regulating NBCe1-A function through its effect on CFTR activity rather than directly regulating ion
