Answer:
#code (count_seq.py)
def count_seq():
n='2'
while True:
yield int(n)
next_value=''
while len(n)>0:
first=n[0]
count=0
while len(n)>0 and n[0]==first:
count+=1
n=n[1:]
next_value+='{}{}'.format(count,first)
n=next_value
if __name__ == '__main__':
gen=count_seq()
for i in range(10):
print(next(gen))
Explanation:
- Start with number 2. Use string instead of integers for easy manipulation
.
- Loop indefinitely
.
- Yield the integer value of current n
.
- Loop until n is an empty string
.
- Loop as long as n is non empty and first digit of n is same as first
.
- Append count and first digit to next_value
.
