SyntaxError in a 'If, elif, else-and'-construct [closed]

I have this python-code:

event_list = []
precipitation_avg_list = [1,2,3,4,5,5,6,7,89,97]

for i in range(len(precipitation_avg_list)): current_precip_value = precipitation_avg_list[i]

if i < len(precipitation_avg_list)-3:   # as long as iterator i hasnt reached the end of the list

    next_precip_value = precipitation_avg_list[i+1]
    next_next_precip_value = precipitation_avg_list[i+2]
    next_next_next_precip_value = precipitation_avg_list[i+3]
    
    if current_precip_value>0:              
        event_list.append(1)
    elif (current_precip_value>0 and next_precip_value=0 and next_next_precip_value>0):
        event_list.append(1)
    elif ((current_precip_value>0) and (next_precip_value=0) and (next_next_precip_value=0) and (next_next_next_precip_value>0)):
        event_list.append(1)
    else:
        event_list.append(0)
else:
    continue

I get the error: 'SyntaxError: invalid syntax. But I dont see what I did wrong in both variants of the elif-blocks.

Do you see it?
