Here is the Python script that extracts daily 5 Psalms ... Psalm 1 to 5 for day 1 of each month, 6 to 10 for day 2 of the month, 11 to 15 for day 3 ... etc...

Save this as a text file as: DailyPsalms.py file in a folder ...

and also save the text file it needs ... see it on the next page ... save that text in the same folder as: 1To150PsalmsFixed.txt


Code: [Select]
#DailyPsalms.py
#2024-02-15

from datetime import date
from sys import exit

fNameFixed = "1To150PsalmsFixed.txt"
try:
    with open(fNameFixed) as f:
        lines = f.readlines() # get lines into Python list called lines
except:
    print("Can't find file", fNameFixed, "... ")
    input("PRESS Enter key to exit ... ")
    exit()
   
#get current date
now = date.today()
day = now.day

print("Today is: {:4d}-{:02d}-{:02d}".format(now.year, now.month, day))
if day == 31: # there are only 150 Psalms
    day = 30
end = day*5
beg = end-4

these = [] # get a Python list of these ...
for x in range(beg, end+1):
    these.append( '(Ps ' + str(x) + ':' )

verses = [] # get todays 5 verses into Python list of verses
for line in lines:
    for text in these:
        if text in line:
            verses.append(line)
           
for line in verses:
    print()
    count = 0
    for ch in line:
        count += 1
        if count <= 40:
            if count == 1 and ch == ' ':
                count = 0
            else:
                print( ch, end = '' )
        else: #count here is > 40
            print(ch, end = '')
            if ch in " .,?!":
                print()
                count = 0
            if ch == '\n':
                count = 0

Or ... can use this more 'classical and memory efficient way' to extract the 5 Psalms for each day ...

Code: [Select]
# 5PsalmsForEachDay.py
# this version: 2024-03-14

from datetime import date
from sys import exit

#get current date
now = date.today()
day = now.day

    day = 30  # for day 31 repeat day 30 Psalms

# get delimits to start and end of today's 5 verses ...   
end = day*5
beg = end-4
startAtStr = '(Ps ' + str(beg) + ':'
endAfterStr = '(Ps ' + str(end) + ':'

verses = [] # construct an empty list

            verses.append(line)
               
        # above stopped at this first line of last chapter for today
        # so get ...
        verses.append(line)

        # now get rest of lines/verses in the last chapter ...
        while (line := f.readline()) and endAfterStr in line:
            verses.append(line)
           
        # when reach here, at end of 5th verse or reached file end         
except:
    print("Can't find file", fNameFixed, \
          " (or some other unexpected error) ... ")
    input("PRESS Enter key to exit ... ")
    exit()

# ok ... now can output the 5 verses formatted to NOT
# much more than 40 charactters per line         
for line in verses:
    print()
    count = 0
    for ch in line:
        count += 1
        if count <= 40:
