问题描述
我正在尝试让此脚本将信息写入基本文本文件.我还在学习python.
I'm trying to get this script to write information into a basic text file. I'm still learning python.
问题出在这里:
file_text = """%s SHOOT DETAILS
Number of shoots: %s
Maximum range: %s
Number of firers: %s
Number of lanes active: %s
Number of details: %s
Troops per detail: %s
RANGE STAFF
Ammo NCO: %s
Medical Supervisor: %s
IC Butts: %s""" % (shoot_name, number_of_shoots, max_range, number_of_firers, number_of_lanes, number_of_details, size_of_details, ammo_nco, medical_supervisor, ic_butts)
错误信息:NameError: name 'number_of_details' 未定义
The error message: NameError: name 'number_of_details' is not defined
上面的内容(据说)是这样写到一个文件中的:
The above is (supposedly) written into a file with this:
def generatedocument():
file = open(file_name, 'w')
file.write(file_text)
os.startfile(file_name)
但是我之前确实在以下函数中定义了它:
However I did define it earlier in the following function:
def detailformation():
number_of_details = number_of_firers / number_of_lanes
return number_of_details
定义的 size_of_details 出现相同的问题:
Identical problems occur for the size_of_details, defined:
def detailsizer():
size_of_details = number_of_firers / detailformation()
return size_of_details
还有范围工作人员选择器功能,有时它会给我一个类似的错误.它们来自这个从列表中随机选择它们的函数:
And also with the range staff chooser function, sometimes it gives me a similar error. They come from this function that randomly selects them from a list:
def range_staff():
print "
"
ammo_nco = (random.choice(fiveplatoon))
print "Ammo NCO: "+ammo_nco
fiveplatoon.remove(ammo_nco)
medical_supervisor = (random.choice(fiveplatoon))
print "Medical supervisor: "+medical_supervisor
fiveplatoon.remove(medical_supervisor)
ic_butts = (random.choice(fiveplatoon))
print "IC Butts/Console: "+ic_butts
fiveplatoon.remove(ic_butts)
return range_staff
似乎我在这里遗漏了一些基本的东西.如何让python识别?
It seems like I'm missing something fundamental here. How can I get python to recognise?
推荐答案
变量只存在于你声明的范围内
The variables only exist in the scope you declare them
def fun():
x = 5
return x
>>> x
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
x
NameError: name 'x' is not defined
如果你想使用一个函数的return
值,那么调用这个函数并将它赋值给这样一个变量
If you want to use the return
value from a function, then call the function and assign it to such a variable
>>> x = fun()
>>> x
5
