我想编写一个程序(姓名,字符串,年龄和身高是至少2位用户的数字)(姓名,年龄,身高)。因此,我尝试使用一会儿True循环,但仅在一个条目(名称,年龄,身高)之后就中断了。这是因为列表中的项目数是树。我如何制作一个元组,以便所有名称,年龄和身高的项目数都可以算作一个?还是有什么简单的方法?
data=[]
while True:
name = raw_input("Please enter your name: ")
age = int(raw_input("Please enter your age: "))
height = int(raw_input("Please enter your height: "))
data.append(name)
data.append(age)
data.append(height)
if len(data) <2:
print "you need to enter at least 2 users"
else:
break
print data

尝试
data=[]
while len(data) < 2:
name = raw_input("Please enter your name: ")
age = int(raw_input("Please enter your age: "))
height = int(raw_input("Please enter your height: "))
data.append({
'name': name,
'age': age,
'height': height,
})
print data
这是因为您放置了name
而不是用户信息(名称,年龄,身高)的决定。

您可以使用range
例如:
data=[]
for _ in range(2):
name = raw_input("Please enter your name: ")
age = int(raw_input("Please enter your age: "))
height = int(raw_input("Please enter your height: "))
data.append((name, age, height))
print(data)
或:使用while循环。
data=[]
while True:
name = raw_input("Please enter your name: ")
age = int(raw_input("Please enter your age: "))
height = int(raw_input("Please enter your height: "))
data.append((name, age, height))
if len(data) == 2:
break
print(data)
