# Program to Find Frequency of each element in a array in Python

Program to Find Frequency of each element in a array in Python. This program contains For loop, Array initialisation, Input and Print commands. This program is for Beginners, class 11, 12 and B Tech computer science students.

### What is an Array ?

An array is defined as a collection of items that are stored at contiguous memory locations.

### What is Frequency ?

Here the frequency of elements refers to the n.o of times a element is repeated.

### Source code:

``````#Enter the length of Array
n= int(input("Enter the length of Array"))
#Intialising a array
a=[None]*n
#running a for loop for the enter of array
for i in range (0,n):
m= int(input( " Enter the content of Array"))
a[i]=m
#for checking the n.o of times a number occuring in an array
for i in range (0,n):
#print (a[i])
count=0

for j in range (0,n):
if a[i]==a[j]:
count= count+1
print(a[i]," number is  occuring  freqency in this much time",count)``````

### Explanation of Source code :

step 1:Enter the length of Array
n= int(input(“Enter the length of Array”))
step 2:Intialising a array
a=[None]*n
step 3:running a for loop for the enter of array
for i in range (0,n):
m= int(input( ” Enter the content of Array”))
a[i]=m
step 4:for checking the n.o of times a number occuring in an array
for i in range (0,n):
step 5:for printing
print (a[i])
count=0
for j in range (0,n):
if a[i]==a[j]:
count= count+1
print(a[i],” number is occuring freqency in this much time”,count)

### Output :

```Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32

Enter the content of Array1
Enter the content of Array2

1  number is  occuring  freqency in this much time 3
2  number is  occuring  freqency in this much time 4
3  number is  occuring  freqency in this much time 2
2  number is  occuring  freqency in this much time 4
3  number is  occuring  freqency in this much time 2
2  number is  occuring  freqency in this much time 4
2  number is  occuring  freqency in this much time 4
>>> ```

### Output Explanation:

The output asks for the input of length size of Array and contents of Array and then prints after calculating the numbers of times the terms is called.

Enter the length of Array9
Enter the content of Array1
Enter the content of Array1
Enter the content of Array1
Enter the content of Array2
Enter the content of Array3
Enter the content of Array2
Enter the content of Array3
Enter the content of Array2
Enter the content of Array2
1 number is occuring freqency in this much time 3
1 number is occuring freqency in this much time 3
1 number is occuring freqency in this much time 3
2 number is occuring freqency in this much time 4
3 number is occuring freqency in this much time 2
2 number is occuring freqency in this much time 4
3 number is occuring freqency in this much time 2
2 number is occuring freqency in this much time 4
2 number is occuring freqency in this much time 4

### Conclusion:

This program is running fine.
