Can I use list comprehension or reduce a for loop for the code?
x=[100,200,300]
y=[10,20,50,70,80]
results=[]
for i in range(len(x)):
temp=[]
for j in range(len(y)):
x[i]+=y[j]
temp.append(x[i])
results.append(temp)
print(results)
Python 3.8 added a neat feature of assignment expressions which is really handy in producing cumulative sums, and can help you replace these loops in a couple of list comprehensions:
total = 0
cumsums = [total := total + t for t in y]
result = [[c+s for c in cumsums] for s in x]
xisn't defined in the snippet you shared.
