Then prefix a cell with the %%cython marker to compile it:
In [2]:
%%cython
cdef int a = 0
for i in range(10):
a += i
print(a)
45
You can show Cython's code analysis by passing the --annotate option:
In [3]:
%%cython -a
def intsum(values):
cdef int value, sum = 0
for value in values:
sum += value
return sum
print(intsum(range(5)))
