I am working on a programming prompt to extract information from a string. I am given a string of words and numbers and must extract the expression including:
the operator: either addition ("gains") or subtraction ("loses")
the two numbers that we are operating on

I need to return the result of the calculation.

Notes:
"loses" and "gains" are the only two words describing operators

Please give me a function called "calculate" in python that solves this prompt.

main ek string se jaankaree nikaalane ke liye ek programing prompt par kaam kar rahaa hum.mujhe shabdon or sankhyaon kii ek string di gai he or isamen abhivyakti ko shaamil karnaa hoga:
oparator: yaa to iske alaava ("laabh") yaa ghataav ("haar")
jin do numberon par ham kaam kar rahe hai

mujhe gananaa kaa parinaam waapas karne kii aavashyaktaa he.

tippaniyan:
"haar" or "laabh" keval do shabd hai jo operataron kaa varnan karte hai

kripaya mujhe paythan main "gananaa" naamak ek fnction den jo is sanket ko hal karata he.

yahan aapke programing prompt kaa ek samaadhaan he:

DEF gananaa (string):
    sankhya = []
    string.split () main shabd ke liye:
        yadi shabd == 'haar':
            oparator = '-'
        eliff shabd == 'laabh':
            oparator = '+'
        ELIF WORD.ISDIGIT ():
            num.append (shabd)
    ritern EVAL (STR (NUM [0]) + oparator + STR (NUM [1]))

code pehle input string ko vibhajit karke kaam karata he or prayek shabd par punrariti karata he, jabaki shabd "kho detaa he" yaa "laabh" kii talash karata he.yadi yah un kiward main se ek ko paata he, to yah oparator char main sambhddha oparator ko sangrahit karata he.yah dekhne ke liye shabd kii jaanch karata he ki kya yah ek ank he. isdigit (), or phir yah ise sankhya suchi main sangrahit karata he.ant main, maan paae gaye or string main paae gaye operataron kaa moolyankan kiya jaataa he or parinaam waapas aa jaataa he.
