我是python的新手,虽然它是一个简单的程序,但我还是坚持了一点 我使用了“Return False”移出函数,但我想完全移出函数。如何做到这一点。 另外,如果我想从pythonshell运行这个脚本,还需要知道如何完成它。你知道吗
def menu():
print "calculator using functions"
print "Choose your option:"
print " "
print "1) Addition"
print "2) Subtraction"
print "3) Multiplication"
print "4) Division"
print "5) Quit calculator.py"
print " "
return input ("Choose your option: ")
def add(a,b):
print a, "+", b, "=", a + b
print " Do you want to continue: "
decide=raw_input("yes or no: ")
if decide== "no" or decide== 'n':
print(" You have exited ")
return False
elif decide=='yes' or decide== 'y':
menu()
else:
print "wrong choice!!!"
return False
# this subtracts two numbers given
def sub(a,b):
print b, "-", a, "=", b - a
# this multiplies two numbers given
def mul(a,b):
print a, "*", b, "=", a * b
# this divides two numbers given
def div(a,b):
print a, "/", b, "=", a / b
loop = 1
choice = 0
while loop == 1:
choice = menu()
if choice == 1:
add(input("Add first No: "),input("Add second No: "))
elif choice == 2:
sub(input("Add first No: "),input("Add second No: "))
elif choice == 3:
mul(input("Add first No: "),input("Add second No: "))
elif choice == 4:
div(input("Add first No: "),input("Add second No: "))
elif choice == 5:
loop = 0
print "End of program!"
退出函数不必显式地
return
任何内容。当解释器到达函数块的末尾时,函数退出。你知道吗在命令行中键入:
Python我的程序.py你知道吗
要从提示符运行程序,如果要使用特定的python shell(bash或cmd除外),则需要查看该特定shell的文档(例如http://www.dreampie.org/)。你知道吗
要退出函数,请使用:
要退出程序,请使用:
您想使用
exit
。它退出程序。你知道吗相关问题 更多 >
