To get the number of elements in a list in Python, you can use the len() function. Here's an example: my_list = [1, 2, 3, 4] num_elements = len(my_list) print(num_elements) # Output: 4 Try it Yourself » Copy Watch a video course Python - The Practic...
'zhangsan'),(1,'lisi'),(2,'wangwu')]#tuple的特性是:拿一个元素接tuple会将整个tuple赋给此元素,拿与tuple长度相等元素接tuple会将tuple的值依次赋给元素#第一种遍历方法forindex,valueinenumerate(L):print(index,'-', value)#第二种方法fortinenumerate(L):print(t[0],'-', value)...
print(tuple1[-1]) # 只有一个int型的tuple tuple2=(1,) print(tuple2[0]) # tuple中有list的情况,list中的元素可以进行增删改 tuple3=('zhangsan','lisi',['wangwu','zhaoliu']) print(tuple3) print(tuple3[-1]) tuple3[-1].append('tianqi') # tuple中的list集合中添加元素 print(tuple3)...

list转tuple c=tuple(a) tuple转list c=list(b) 四、set集合 在Python中set的形式长这个样子: {1,2,3} 首先,大括号括起来;其次,一组元素之间无序,所以不能用下标查询,只能用in操作查询;另外,元素唯一,插入重复元素无效。 1 2 3 操作Python 增 a.add(),注意插入重复元素无效 删 a.remove(),pop在...
We simply need to iterate over all the elements of the list and then for each element create a tuple consisting of the element and its cube and then append it to a list.This can be done by simply loop and also to shorten the code we can use comprehension techniques. He...
This sequence can be a list, a tuple, a string or other ordered collection of elements. Other sequences like sets are not accepted as arguments to this method and a TypeError is raised. This is because sets are considered as unordered sequences and do not record the element positions ...
In the example given below we have created a tuple and a list of elements. Then the modf() method is used to retrieve the fractional and integer part of the tuple and list elements at the specified index:Open Compiler # importing the math module from math import modf Tuple = (-76.43, ...
