Python Pandas replacing nan's in one column conditional on observations in another column

it fixes the issue This was a bit more annoying to code, basically we can apply a custom function that performs the lookup for you:
In [106]:
# define our function
def func(x):
    # test to see if the asterisk is present
    if x.find('*') > 0:
        # perform a lookup on a slice of the passed in string
# using loc assign to column 'Y' where it is null the returned calculation of the apply
current_data.loc[current_data.Y.isnull(),'Y'] = current_data[current_data.Y.isnull()]['X'].apply(func)
      X   Y
0  3*NY   4
1     3   4
2     2   5
3  2*NY   5
4     1   8
5     7 NaN

fixed the issue. Will look into that further This is a response to your second question (you should stick to one question per post).
df.loc[:, ['e0', 'e1']].apply(lambda x: x.str.strip())

Replacing conditional with something?

I wish this help you The pattern I would use here is just encapsulation. The nesting here is hard to follow, and worsened by the equality comparisons. If possible, instead of exposing the raw field, try encapsulating the intent.
e.g. Instead of if (data.ApplicationPurpose == ApplicationPurpose.Renewal) try extending ApplicationStatusData with a property like
bool IsRenewalApplication 
  return this.ApplicationPurpose == ApplicationPurpose.Renewal;

Replacing DataFrame index values in python with conditional argument

like below fixes the issue In pandas for replace values in index or columns is used function rename:
df = df.rename(d)
print (df)
South Korea         12
United States       13
United Kingdom      14
Hong Kong           15
df = pd.concat([df] * 100000)

In [11]: %timeit df.rename(d)
10 loops, best of 3: 75.7 ms per loop

In [12]: %timeit pd.Series(df.index).replace(d)
10 loops, best of 3: 71.8 ms per loop

In [13]: %timeit pd.Series(df.index.values).replace(d)
10 loops, best of 3: 75.3 ms per loop
