为什么我的列表是空的
temp = int(input("请输入数字："))list1 = []
while temp > 0:
num = temp % 2
temp//=2
list1.append(num)
shengyu = len(list1)
str1 = ""
while temp == 0 and shengyu > 1:
str1 = str1 + str(list1.pop())
print(str1)
请输入数字：10
Traceback (most recent call last):
File "C:\Users\945\Desktop\实验\python\十进制转二进制.py", line 10, in <module>
str1 = str1 + str(list1.pop())
IndexError: pop from empty list
求解谢谢各位大佬
你取字符串的while循环有问题
改temp = int(input("请输入数字："))
list1 = []
while temp > 0:
num = temp % 2
temp//=2
list1.append(num)
str1 = "0b"
for i in list1[:]: #这里必须切片复制，不然会出错
str1 = str1 + str(list1.pop())
print(str1)
for i in list1[:]: #这里必须切片复制，不然会出错
这句代码没看懂大佬解释一下好么
