The operation law of GRC flow graph

Hi,guys
I am writing a simple embedded python block program, the content of the program work function is as follows:
def __init__(self):  # only default arguments here
"""arguments to this function show up as parameters in GRC"""
gr.sync_block.__init__(
self,
name='random limit source',   # will show up in GRC
in_sig = None,
out_sig = [np.complex64]
def work(self, input_items, output_items):
for i in range(10) :
if i == 0:
output_items[0][i] = 0.5+0.5j
print("linge1")
elif i == 1:
output_items[0][i] = 0.24+0.5j
print("linge2")
elif i == 2:
output_items[0][i] = 0.35+0.62j
print("linge3")
elif i == 3:
output_items[0][i] = 0.47+0.33j
print("linge4")
elif i == 4:
output_items[0][i] = 0.72+0.21j
print("linge5")
elif i == 5:
output_items[0][i] = 0.12+0.65j
print("linge6")
elif i == 6:
output_items[0][i] = 0.23+0.57j
print("linge7")
elif i == 7:
output_items[0][i] = 0.85+0.23j
print("linge8")
elif i == 8:
output_items[0][i] = 0.86+0.56j
print("linge9")
else:
output_items[0][i] = 0.14+0.57j
print("linge10")
return len(output_items[0])

According to the content of the program, my first ten outputs will be the number I specified, so will the number I didn't specify be 0? I observe its output, it will continuously loop the work function according to the sampling rate, and print the "linge." character every once in a while. Is this the working rule of GRC? How can I make it only output ten prescribed numbers without continuing the subsequent loop?

Sincerely
