Pandas Sans Lambdas

Pandas method chaining using assign or loc usually means using lambdas. These get repetitive and reduce readability. Pandas Sans Lambdas is a solution to this. Here's an example:

import pandas as pd
from pandas_sans_lambdas import col

df = pd.DataFrame({"a": [1,2,3], "b": [4,5,6]})

# The old way
df = df.assign(with_lambdas = lambda DF: DF["a"] ** 2 / DF["b"])

# The new way
df = df.assign(sans_lambdas = col("a") ** 2 / col("b"))

print(df)

Hopefully you agree that this is more readable!
