Answer 1

Use month_name instead of month_abbr .

SMonth = df['NMonth'].apply(lambda x: calendar.month_name[x])

You could have found this answer yourself in the docs: https://docs.python.org/3.5/library/calendar.html#calendar.month_name

Answer 2

I think here is better use map by dictionary:

months = ['January','February','March','April','May','June','July','August',
          'September','October','November','December']

d = {'{:02d}'.format(i+1):months[i] for i in range(12)}
print (d)
{'05': 'May', '01': 'January', '06': 'June', '11': 'November', 
'04': 'April', '12': 'December', '09': 'September', '08': 'August', 
'03': 'March', '07': 'July', '10': 'October', '02': 'February'}

SMonth=df['NMonth'].map(d)
print (SMonth)

0     January
1    February
2       March
Name: NMonth, dtype: object
