Inspired by R P Herrold's challenge.
Some ways of splitting data in Python follow.
In [1]:
MONTH_NDAYS = '''
0:31
1:29
2:31
3:30
4:31
5:30
6:31
7:31
8:30
9:31
10:30
11:31
'''.split()
In [2]:
MONTH_NDAYS
Out[2]:
In [3]:
for month_n_days in MONTH_NDAYS:
month, n_days = map(int, month_n_days.split(':'))
print(f'{month} has {n_days}')
Tuple unpacking is nice and in this case enables DRY (aka Single Source of Truth) code. Compare:
month, n_days = month_n_days.split(':')
with
FUTLHS=`echo "$j" | awk -F: {'print $1'}`
FUTRHS=`echo "$j" | awk -F: {'print $2'}`One can do all the chopping up front. The chopping code is less readable, but the subsequent for loop is just pretty.
In [4]:
MONTH_NDAYS = [list(map(int, s.split(':'))) for s in '''
0:31
1:29
2:31
3:30
4:31
5:30
6:31
7:31
8:30
9:31
10:30
11:31
'''.split()]
In [5]:
MONTH_NDAYS
Out[5]:
In [6]:
for month, n_days in MONTH_NDAYS:
print(f'{month} has {n_days}')
Unnesting the chopping code makes it easier to read. The for loop is still pretty.
In [7]:
MONTH_NDAYS = '''
0:31
1:29
2:31
3:30
4:31
5:30
6:31
7:31
8:30
9:31
10:30
11:31
'''.split()
MONTH_NDAYS
Out[7]:
In [8]:
MONTH_NDAYS = [s.split(':') for s in MONTH_NDAYS]
MONTH_NDAYS
Out[8]:
In [9]:
MONTH_NDAYS = [list(map(int, x)) for x in MONTH_NDAYS]
MONTH_NDAYS
Out[9]:
In [10]:
for month, n_days in MONTH_NDAYS:
print(f'{month} has {n_days}')
