python - 基本字典脚本

我想制作一个程序，将清单作为字典数据，并在底部打印总数。

# inventory.py
stuff = {"coal":42,"dagger":1,"iron":
20,"torch":2}
total_items = 0

def display_inventory(inventory):
       for k,v in inventory.items():
              print(k,v)
              global total_items
              total_items = total_items + v

print("\n")
print("Total: " + str(total_items))

我想在输出中添加冒号，例如：
煤：42
匕首：2
我该怎么做呢？

编辑：我们使用变量“ stuff”来调用函数

最佳答案

您可以使用字符串格式，代码看起来优雅，更多细节在这里https://www.programiz.com/python-programming/methods/string/format

# inventory.py
stuff = {"coal":42,"dagger":1,"iron":
20,"torch":2}
total_items = 0

def display_inventory(inventory):
       for k,v in inventory.items():
              print("{}:{}".format(k,v))
              global total_items
              total_items = total_items + v

print("\n")
print("Total: " + str(total_items))
