I am trying to find a way to convert a time string like "last Sunday" or "Next Monday" into DateTime format using python 3. I tried out using the follwoing:
x = datetime.strptime("Sunday", "%A")
but it gave a output like this:
1900-01-01 00:00:00
I want to know how to get the Date in relation to the current Date!
Thank you :)
My suggestion: Build up a helper index to find out how many days ahead or before the day is and then work with timedelta
. The following code should showcase what I mean, not super Pythonic but it does the trick for your examples.
from datetime import datetime
from datetime import timedelta
now = datetime.now()
nowDayString = now.strftime("%A")
days = [
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday",
"Sunday"
]
def buildLut():
floatingDays = [""]*8
for idx, day in enumerate(days):
if day == nowDayString:
floatingDays[0] = nowDayString
floatingDays[7] = nowDayString
for i, j in zip(range(idx+1, len(days)), range(1, len(days))):
floatingDays[j] = days[i]
for i in range(idx):
floatingDays[7-(idx-i)] = days[i]
return floatingDays
def findme(s):
td = timedelta()
dayToLookFor = s.split(" ")[1]
if "last" in s.lower():
td = timedelta(days=-(7 - floatingDays.index(dayToLookFor)))
elif "next" in s.lower():
td = timedelta(days=floatingDays.index(dayToLookFor))
return now + td
floatingDays = buildLut()
print(floatingDays)
print(findme("last Sunday"))
print(findme("Next Monday"))
