# Solved: python consecutive numbers difference between

The main problem related to Python consecutive numbers difference between is that the difference between two consecutive numbers is not always the same. For example, if you have a list of numbers [1, 2, 3], the difference between 1 and 2 is 1, but the difference between 2 and 3 is only 0.5. This can cause confusion when trying to calculate differences in values or when using algorithms that rely on a constant step size.

```
def consecutive_difference(nums):
diff = []
for i in range(len(nums)-1):
diff.append(abs(nums[i] - nums[i+1]))
return diff

# Driver code
nums = [2, 4, 6, 8]
print(consecutive_difference(nums))```

# Line 1: This line defines a function called consecutive_difference that takes in one argument, nums.
# Line 2: This line creates an empty list called diff.
# Line 3: This line is a for loop that iterates through the length of nums minus one.
# Line 4: This line adds the absolute value of the difference between each element in nums to the diff list.
# Line 5: This line returns the diff list after it has been populated with all of the differences between consecutive elements in nums.
# Line 8: This line sets a variable called nums equal to a list containing 2, 4, 6, and 8.
# Line 9: This line prints out the result of calling consecutive_difference on nums.

## Find consecutive numbers in a list in Python

Finding consecutive numbers in a list in Python is relatively easy. The most straightforward approach is to loop through the list and compare each element with the one before it. If the difference between two elements is 1, then they are consecutive numbers.

Here’s an example of how this can be done:

numbers = [1,2,3,4,5,6] # List of numbers
consecutive_numbers = [] # List to store consecutive numbers
for i in range(len(numbers)-1): # Loop through list
if (numbers[i+1] – numbers[i]) == 1: # Check if difference between two elements is 1
consecutive_numbers.append(numbers[i]) # Append element to list of consecutive numbers
consecutive_numbers.append(numbers[i+1]) # Append next element to list of consecutive numbers
print(consecutive_numbers) # Print out list of consecutive numbers

## Get the difference between consecutive numbers in a list

In Python, you can get the difference between consecutive numbers in a list by using the zip() function. The zip() function takes two or more iterables and returns an iterator of tuples. The first item in each passed iterable is paired together, then the second item in each passed iterable are paired together, and so on. To get the difference between consecutive numbers in a list, you can use zip() to pair up each number with its predecessor and then subtract them to get the difference. For example:

list_numbers = [1, 2, 3, 4]
differences = [y – x for x, y in zip(list_numbers[:-1], list_numbers[1:])]
print(differences) # Output: [1, 1, 1]
