Introduction

In this section of python programming, we will discuss the different ways to clear the list. Python provides four ways to clear :

• Using clear(): Clear the list to size zero (empty list)
• Using reinitialization: Reinitializing the list with empty value
• Using *=0: Removes all the element
• Using delete statement: Deletes all the values if no range is provided (i.e. list[:])

Program

list1 = ['is', 'at', 'around', 'in', 'the' ]
list2 = ['red', 'blue', 'black', 'green', 'grey']
list3 = [1, 2, 3, 4, 5]
list4 = [6, 9, 10, 7, 11]
# Using clear
print("Elements in list1: ",list1)
list1.clear()
print("Elements after using clear():",list1)
#Reinitialization
print("Elements in list2: ",list2)
list2 = []
print("Elements after using reinitialization:",list2)
# Using *= 0
print("Elements in list3: ",list3)
list3 *= 0
print("Elements after using *= 0:", list3)
# Using del
print("Elements in list4: ",list4)
del list4[:]
print("Elements after using del:",list4)

Output

Explanation

In the above python code we have created four lists with different values. We have used the different ways (mention above) to clear the list.
