##---Initializing Variable----------------------------------------------------------------------#
#-----------------------------------------------------------------------------------------------#
objectMass=0
weight=0

##---Introductory Statement: Welcome to the Program---------------------------------------------#
#-----------------------------------------------------------------------------------------------#
def intro():

              "Hello and Welcome to Mass to Weight Calculator",
              "Today is a good day!",
              "---------------------------------------------------------"]))

##---The getMass module gets user input for mass & stores in getMass reference modules----------#
#-----------------------------------------------------------------------------------------------#
def getMass(): 
    objectMass=float(input("Please enter the Mass of the object you want calculated: "))
    return objectMass

##--The weightConversion module calculates inputted mass into weight----------------------------#
#-----------------------------------------------------------------------------------------------#
def weightConversion(objectMass):
    gravity = 9.8
    weight=float(objectMass)*gravity
    return weight

##--Calculation Module compares weight of object and prints out sentence associated to weight---#
#-----------------------------------------------------------------------------------------------#
def massToWeight(objectMass, weight):
    if weight > 1000:
        print("\n".join(["Holy Smokes, your weight(in newtons) is:", format(weight, ".2f"),
                        "It's way too heavy!!!"]))

    if weight < 10:
        print("Aww man, I can pick this up with one finger.", "It's way too light!",
                        "This weight(in newtons) is:", format(weight, ".2f"))

    else:

    return

##---Main module--------------------------------------------------------------------------------#
#-----------------------------------------------------------------------------------------------#
def main():
    ##Introductory Statement
    intro()

    ##---Get Mass
    objectMass=getMass()

    ##Calculate Mass to Weight
    weight=weightConversion(objectMass)

    ##Compare results
    massToWeight(objectMass, weight)

    ##Closing Statement
    closingStatement()

main()

嘿大家好我的第一个条件是＆gt;我的程序正在返回我的其他程序massToWeight模块中满足1000并且不确定原因。该程序不需要模块，但希望在python中练习使用模块。

有人可以帮忙吗？

谢谢，

Answer 1

if weight > 1000:                         #IF1
    print()
if weight < 10:                           #IF2
    print()
else:
    print()

问题是IF2应该是elif

让我们考虑一个例子：

让重量= 10000
IF1条件将通过，它将被执行。
现在，由于IF2不是elif，因此这将被视为一个完全独立的新If-else语句。
IF2条件将失败，然后else部分将被执行。

Answer 2

使用

elif weight < 10:

而不是

if weight < 10:

无论是否在Python中满足条件，都返回else语句
