There are some most important functions of list data structure which we can use in our script without knowing the internal structure of the functions.
len() function: This function will give us the length of the list.
l=[1,2,"mayank",3]
x=len(l)
print(x) # 4
index(): This method is used to find out the index of any element in the list.
The usage of this function can be as:
l=list()
l=[1,2,3,4,5]
print(l.index(3)) #2
index() method gives IndexError if we have not supplied a right index to this function.
Another usage of index() method is as:
l=[1,2,3,4]
i=l.index(2,3) # will start find index of two and searching will start from index 3
print(i) # gives ValueError
reverse() function: This function will reverse the element of the whole list.
l=[1,2,3]
l.reverse()
print(l) # [3,2,1]
sort() function: This method is used to sort the given list.
l=[2,5,1,4,6,2]
l.sort()
print(l) # [1,2,2,4,5,6]
clear() function: This function is used to delete all elements from the list.
The usage of this function is as follows:
l=[1,2,3,4]
l.clear()
print(l) #[]
max() function: This function returns the maximum value from the given list.
A simple script to demonstrate this function is as:
l=[2,3,5,2,6,6,4]
m=max(l)
print(m) #6
min() function: This function returns the maximum element from the list.
The script can be as:
l=[1,2,,5,2,5]
m=min(l)
print(m) #1
sum() function: This method returns the sum of all values present in the list.
example:
l=[1,2,3,4]
s=sum(l)
print(s) #10
len() function: This function will give us the length of the list.
l=[1,2,"mayank",3]
x=len(l)
print(x) # 4
index(): This method is used to find out the index of any element in the list.
The usage of this function can be as:
l=list()
l=[1,2,3,4,5]
print(l.index(3)) #2

l=[1,2,3,4]
i=l.index(2,3) # will start find index of two and searching will start from index 3
print(i) # gives ValueError

s=sum(l)
print(s) #10
