Question

我正在使用此BMI计算器代码，但是当我运行程序并输入所有值时，它给出了答案，但仍在重复。我希望程序在给出答案后终止。 我也希望答案以小数点表示。

下面是代码：-

import math
print "*After Entering Every value Hit Enter"
time.sleep(2)

#intro Starts
name = raw_input("Please Enter Your Name : ") #enter your name
print""
print "Hello", name
time.sleep(0.5)
print""
print "It Feels Like Your Are Really Concerned About Your Health"
time.sleep(3)
print "So Lets Start Calculating Your BMI"
print "" #intro ends

#option for gender
gender = raw_input('Are you Male Or female ? ')
print "OK, Thats great"
print ""
#the bmi Calculation
kg = float(input('Enter Your Weight(in Kg.) : '))
cm = float(input('Enter Your height(in cm)  : '))
print "" 
meter = cm * math.pow(10, -2)
bmi = float(kg//(meter**2))

#the Conditions start
while gender == "male":
     if bmi < 18.5: #if overweight
        print "It seems like your are Underweight"
        print "Your BMI is", bmi
        print ("")
        print "I prefer you To Increase Your diet."
    #if normal
    elif bmi >= 18.5 and bmi <= 25:
        print "Your are Absolutely fine"
        print "Your BMI is", bmi
        print "Be on the same track"
    #if overweight
    elif bmi > 25 and bmi <=30:
        print "Your are overweight "
        print "Your BMI is", bmi
        print "I prefer you to go for daily morning Jog."
    #if obese
    elif bmi > 30:
        print "Your are under obese category"
        print "Your BMI is", bmi
        print "I prefer you to Change your diet"
while gender == "female" or "Female" :
   print "sorry this program is under development"
print ("")

如果有人帮助我，我将很感激。我是初学者

因此，如果您不想重复此过程，则应尝试考虑使用if而不是while

import math
import time
print "*After Entering Every value Hit Enter"
time.sleep(2)

#intro Starts
name = raw_input("Please Enter Your Name : ") #enter your name
print""
print "Hello", name
time.sleep(0.5)
print""
print "It Feels Like Your Are Really Concerned About Your Health"
time.sleep(3)
print "So Lets Start Calculating Your BMI"
print "" #intro ends

#option for gender
gender = raw_input('Are you Male Or female ? ')
print "OK, Thats great"
print ""
#the bmi Calculation
kg = float(input('Enter Your Weight(in Kg.) : '))
cm = float(input('Enter Your height(in cm)  : '))
print "" 
meter = cm * math.pow(10, -2)
bmi = float(kg//(meter**2))

#the Conditions start
if gender == "male":
    if bmi < 18.5: #if overweight
        print "It seems like your are Underweight"
        print "Your BMI is", bmi
        print ("")
        print "I prefer you To Increase Your diet."

    elif bmi >= 18.5 and bmi <= 25:
        print "Your are Absolutely fine"
        print "Your BMI is", bmi
        print "Be on the same track"
    #if overweight
    elif bmi > 25 and bmi <=30:
        print "Your are overweight "
        print "Your BMI is", bmi
        print "I prefer you to go for daily morning Jog."
    #if obese
    elif bmi > 30:
        print "Your are under obese category"
        print "Your BMI is", bmi
        print "I prefer you to Change your diet"
if gender in ("female" ,"Female" ):  #gender == "female" or "Female"  is always true
print "sorry this program is under development"
print ("")

Answer 2

使用break命令中断循环：

while gender == "male":
     if bmi < 18.5: #if overweight
        print "It seems like your are Underweight"
        print "Your BMI is", bmi
        print ("")
        print "I prefer you To Increase Your diet."
    #if normal
    elif bmi >= 18.5 and bmi <= 25:
        print "Your are Absolutely fine"
        print "Your BMI is", bmi
    break

此外，别忘了在循环结束时添加等待，这样程序就不会在完成后立即退出：

import time
time.sleep(100)

您编辑了代码，所以我也编辑和改进了您的代码：

while gender == "male":
     if bmi < 18.5: #if overweight
        print "It seems like your are Underweight"
        print "Your BMI is", bmi
        print ("")
        print "I prefer you To Increase Your diet."
    #if normal
    elif bmi <= 25:
        print "Your are Absolutely fine"
        print "Your BMI is", bmi
        print "Be on the same track"
    #if overweight
    elif bmi <=30:
        print "Your are overweight "
        print "Your BMI is", bmi
        print "I prefer you to go for daily morning Jog."
    #if obese
    elif bmi > 30:
        print "Your are under obese category"
        print "Your BMI is", bmi
        print "I prefer you to Change your diet"
    break
while gender.lower() == "female":
   print "sorry this program is under development"
print ("")

Edit2：

我刚刚尝试运行您的程序。您的代码有很多错误和错误。您不是在导入time而是在等待它。 \n表示换行符。无需编写print ""，而只需在旧的\n语句中您想在新行插入print的地方。如果我们用性别写Male，那么条件将不会运行。请尝试以下操作：

import math,time
print "*After Entering Every value Hit Enter"
time.sleep(2)

#intro Starts
name = raw_input("Please Enter Your Name : ") #enter your name
print "\nHello\n", name
time.sleep(0.5)
print "It Feels Like Your Are Really Concerned About Your Health"
time.sleep(3)
print "So Lets Start Calculating Your BMI\n"

#option for gender
gender = raw_input('Are you Male Or female ? ')
gender = gender.lower()
if gender != "male" and gender != "female":
    print "Invalid Gender"
    time.sleep(10)
    quit()
print "OK, Thats great\n"
#the bmi Calculation
kg = float(input('Enter Your Weight(in Kg) : '))
cm = float(input('Enter Your height(in cm) : '))
print "" 
meter = cm * math.pow(10, -2)
bmi = float(kg//(meter**2))

#the Conditions start
while gender == "male":
    if bmi < 18.5: #if overweight
        print "It seems like your are Underweight\nYour BMI is\n", bmi,"\nI prefer you To Increase Your diet."
    elif bmi < 25:
        print "Your are Absolutely fine\nYour BMI is", bmi,"\nBe on the same track\n"
    elif bmi <=30 :
        print "Your are overweight \nYour BMI is", bmi,"\nI prefer you to go for daily morning Jog."
    elif bmi > 30:
        print "Your are under obese category\nYour BMI is", bmi,"\nI prefer you to Change your diet"
    break
while gender == "female":
   print "Sorry! this program is under development"
   break
print ("")
