I am not able to find out any issue here in my code.
Can anybody please help me find out the problem in the code !!!
days = ['saturday', 'sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday']
for i in range(int(input())):
all_dur = list()
S,E,L,R = map(str, input().split())
L = int(L)
R = int(R)
if days.index(S) < days.index(E):
# currently this is minimum duration
dur = (days.index(E) - days.index(S)) + 1
else:
# currently this is minimum duration
dur = (len(days) - (days.index(S) + 1)) + (days.index(E)+1) + 1
while dur <= R and len(all_dur) < 2:
if dur >= L:
all_dur.append(dur)
dur += 7
if len(all_dur) == 1:
print(all_dur[0])
elif len(all_dur) == 0:
print("impossible")
elif len(all_dur) > 1:
print("many")
