我到处搜索,在任何地方都找不到答案,我的代码遇到了问题,我正在尝试用peewee做一个简单的清单。我遇到的只是这个错误。
File "inventario.py", line 38
if selection =='1':
^
IndentationError: unindent does not match any outer indentation level
我读过与空格混合的制表符可以实现这一目标,已经检查过,甚至使用了SublimeText必须用空格替换制表符的工具。
from peewee import *
db = SqliteDatabase('stockpy.db') #creates db
class Product(Model): #data to create product table
id_prod = IntegerField()
name = CharField()
price = IntegerField()
stock = IntegerField()
class Meta:
database = db #tells which db to use
Product.create_table() #creates table
def newProd(id_prod, name, price, stock):
Product.create(id_prod = id_prod, name = name, price = price, stock = stock) #adds new product with input
def deleteProd(name): #Deletes de product with the given name
todelete = Product.get(Product.name == name)
todelete.delete_instance()
def viewStock():
for name in Product.select(): #shows whats in the table
print Product.id_prod, Product.name, Product.price, Product.stock
menu = {} #simple menu
menu['1']="Add product."
menu['2']="Delete product."
menu['3']="View stock"
menu['4']="Exit"
while True:
options=menu.keys()
options.sort()
for entry in options:
print entry, menu[entry]
selection=raw_input("Please Select:")
if selection =='1':
print "Need the following data:"
id_prod = raw_input("Product id: ")
int(id_prod)
name = raw_input("Product name: ")
price = raw_input("Product price: ")
int(price)
stock = raw_input ("How many are there: ")
int(stock)
print "You're adding the following data", id_prod, name, price, stock
newProd()
elif selection == '2':
name = raw_input ("Enter the name of the product you want to delete: ")
deleteProd(name)
elif selection == '3':
print "Here's your stock"
viewStock()
elif selection == '4':
print "Goodbye"
break
else:
print "Unknown Option Selected!"
任何帮助或提示将不胜感激。提前谢谢。
缩进需要保持一致。 选择一个缩进大小(建议使用 4 个空格)并坚持使用。 每行应在此缩进大小的某个倍数缩进。
我已经用每行前面的空格数注释了您的代码(请注意不一致之处):
menu = {} #simple menu # 0
menu['1']="Add product." # 0
menu['2']="Delete product." # 0
menu['3']="View stock" # 0
menu['4']="Exit" # 0
while True: # 0
options=menu.keys() # 2
options.sort() # 2
for entry in options: # 2
print entry, menu[entry] # 8
selection=raw_input("Please Select:") # 8
if selection =='1': # 3
print "Need the following data:" # 8
id_prod = raw_input("Product id: ") # 8
int(id_prod) # 8
name = raw_input("Product name: ") # 8
price = raw_input("Product price: ") # 8
int(price) # 8
stock = raw_input ("How many are there: ") # 8
int(stock) # 8
print "You're adding the following data", id_prod, name, price, stock # 8
newProd() # 6
elif selection == '2': # 3
name = raw_input ("Enter the name of the product you want to delete: ") # 8
deleteProd(name) # 7
elif selection == '3': # 3
print "Here's your stock" # 8
viewStock() # 8
elif selection == '4': # 3
print "Goodbye" # 9
break # 9
else: # 3
print "Unknown Option Selected!" # 9
我想这就是你想要的:
from peewee import *
db = SqliteDatabase('stockpy.db') #creates db
class Product(Model): #data to create product table
id_prod = IntegerField()
name = CharField()
price = IntegerField()
stock = IntegerField()
class Meta:
database = db #tells which db to use
Product.create_table() #creates table
def newProd(id_prod, name, price, stock):
Product.create(id_prod=id_prod,
name=name,
price=price,
stock=stock) #adds new product with input
def deleteProd(name): #Deletes de product with the given name
todelete = Product.get(Product.name == name)
todelete.delete_instance()
def viewStock():
for name in Product.select(): #shows whats in the table
print Product.id_prod, Product.name, Product.price, Product.stock
menu = {} #simple menu
menu['1'] = "Add product."
menu['2'] = "Delete product."
menu['3'] = "View stock"
menu['4'] = "Exit"
while True:
options = menu.keys()
options.sort()
for entry in options:
print entry, menu[entry]
selection=raw_input("Please Select:")
if selection =='1':
print "Need the following data:"
id_prod = raw_input("Product id: ")
int(id_prod)
name = raw_input("Product name: ")
price = raw_input("Product price: ")
int(price)
stock = raw_input ("How many are there: ")
int(stock)
print "You're adding the following data", id_prod, name, price, stock
newProd()
elif selection == '2':
name = raw_input ("Enter the name of the product you want to delete: ")
deleteProd(name)
elif selection == '3':
print "Here's your stock"
viewStock()
elif selection == '4':
print "Goodbye"
break
else:
print "Unknown Option Selected!"
我不得不猜测一些缩进,因为我不清楚哪些东西是哪些块的一部分。
您需要一个正确处理缩进的编辑器。为获得最佳效果,请始终缩进每个缩进级别使用四个空格。
