I am learning python and try to analyze the code performance by line. I installed line_profiler but it always showed the
UnicodeEncodeError: 'charmap' codec can't encode characters in position 30-31: character maps to undefined
I tried to run chcp 65001 which didn't work.
import cgi
import time
from line_profiler import LineProfiler
def test2():
print('hello!test2()')
def test1():
html='''<script>alert("you are a good boy!&I like you")</scrpit>'''
test2()
escape_html=cgi.escape(html)
for item in range(5):
time.sleep(1)
print(escape_html)
if __name__=='__main__':
lp=LineProfiler()
lp.add_function(test2)
lp_wrap=lp(test1)
lp_wrap()
lp.print_stats()
The results:
hello!test2()
