using boolean in python from inputs -


   phonevalue=0    if (condition== "new"):         phonevalue=int(phonevalue+10)     else:         phonevalue=int(phonevalue+9)     if gps==bool(input("true")):         phonevalue=int(phonevalue+1)     else:         phonevalue=int(phonevalue)      if wifi==eval(bool(input("true"))):         phonevalue=int(phonevalue+1)     else:         phonevalue=int(phonevalue)      if camera==eval(bool(input("true"))):         phonevalue=int(phonevalue+1)     else:         phonevalue=int(phonevalue)     global phonevalue 

this code. supposed able input condition, gps, camera, , wifi , code evaluates input , gives points each condition. if phone new gets ten points , if used gets nine. gps, camera, , wifi wants me use boolean either give point true or no points false. wondering how convert input string boolean in order add phone value?

there's lot wrong in code. firstly, input() command defined

input([prompt])

if prompt argument present, written standard output without trailing newline.

which means call input("true") prints "true" on console , waits line of input. that's not hoping for.

your use of eval bad. every use of eval on user input problem. saved here accident: eval(bool(text)) superfluous. thing bool() can return true or false neither of dangerous eval, since had boolean in hand, eval'ing didn't anything.

converting result of integer addition int() useless, , if / else clauses can more written as:

if input("is there gps? "):     phonevalue += 1 

with no else clause needed. unfortunately, has no chance of getting correct input. if type "true" if block trigger. trigger if write "no", "false", or "josedusol", evaluated true also. declaration @ end

global phonevalue 

does absolutely nothing last line. in fact, should forget global exists because uses incorrectly.

there more faults in code, , should assistance teacher or better learning resource.
