I'd like to do this to pass a string to a Cython code:
# test.py
s = "Bonjour"
myfunc(s)
# test.pyx
def myfunc(char *mystr):
cdef int i
for i in range(len(mystr)): # error! len(mystr) is not the length of string
print mystr[i] # but the length of the *pointer*, ie useless!
but as shown in comment, here it doesn't work as expected.
The only workaround I've found is passing also the length as parameter of myfunc
. Is it correct? Is it really the simplest way to pass a string to a Cython code?
# test.py
s = "Bonjour"
myfunc(s, len(s))
# test.pyx
def myfunc(char *mystr, int length):
cdef int i
for i in range(length):
print mystr[i]
The simplest, recommended way is to just take the argument as a Python string:
def myfunc(str mystr):
