# Python Exercise: Check the numbers that are higher than the previous

## Python Basic - 1: Exercise-148 with Solution

A Python list contains some positive integers. Write a Python program to count the numbers that are greater than the previous number on the list.

**Sample Data:**

([1, 4, 7, 9, 11, 5]) -> 4

([1, 3, 3, 2, 2]) -> 1

([4, 3, 2, 1]) -> 0

**Sample Solution-1:**

**Python Code:**

```
def test(nums):
ctr = 0
for i in range(1,len(nums)):
if nums[i] > nums[i-1]:
ctr += 1
return ctr
nums = [1, 4, 7, 9, 11, 5]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
nums = [1, 3, 3, 2, 2]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
nums = [4, 3, 2, 1]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
```

Sample Output:

Original list of numbers: [1, 4, 7, 9, 11, 5] Count the numbers of the said list that are greater than the previous number! 4 Original list of numbers: [1, 3, 3, 2, 2] Count the numbers of the said list that are greater than the previous number! 1 Original list of numbers: [4, 3, 2, 1] Count the numbers of the said list that are greater than the previous number! 0

**Sample Solution-2:**

**Python Code:**

```
def test(nums):
return sum(nums[n]>nums[n-1] for n in range(1,len(nums)))
nums = [1, 4, 7, 9, 11, 5]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
nums = [1, 3, 3, 2, 2]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
nums = [4, 3, 2, 1]
print("Original list of numbers:", nums)
print("Count the numbers of the said list that are greater than the previous number!")
print(test(nums))
```

Sample Output:

Original list of numbers: [1, 4, 7, 9, 11, 5] Count the numbers of the said list that are greater than the previous number! 4 Original list of numbers: [1, 3, 3, 2, 2] Count the numbers of the said list that are greater than the previous number! 1 Original list of numbers: [4, 3, 2, 1] Count the numbers of the said list that are greater than the previous number! 0
