From Wikipedia:
A bigram or digram is a sequence of two adjacent elements from a string of tokens, which are typically letters, syllables, or words. A bigram is an n-gram for n=2. The frequency distribution of every bigram in a string is commonly used for simple statistical analysis of text in many applications, including in computational linguistics, cryptography, speech recognition, and so on.
Original list:
['Sum all the items in a list', 'Find the second smallest number in a list']
Bigram sequence of the said list:
[('Sum', 'all'), ('all', 'the'), ('the', 'items'), ('items', 'in'), ('in', 'a'), ('a', 'list'), ('Find', 'the'), ('the', 'second'), ('second', 'smallest'), ('smallest', 'number'), ('number', 'in'), ('in', 'a'), ('a', 'list')]

## List: Cheat Sheet

Making a list:

```colors = ['Red', 'Blue', 'Green', 'Black', 'White']
```

Accessing elements:

```# Getting the first element
first_col = colors[0]
# Getting the second element
second_col = colors[1]
# Getting the last element
```

Modifying individual items:

```# Changing an element
colors[0] = 'Yellow'
colors[-2] = 'Red'
```

```# Adding an element to the end of the list
colors.append('Orange')
# Starting with an empty list
colors = []
colors.append('Red')
colors.append('Blue')
colors.append('Green')
# Inserting elements at a particular position
colors.insert(0, 'Violet')
colors.insert(2, 'Purple')
```

Removing elements:

```# Deleting an element by its position
del colors[-1]
# Removing an item by its value
colors.remove('Green')
```

Popping elements:

```# Pop the last item from a list
most_recent_col = colors.pop()
print(most_recent_col)
# Pop the first item in a list
first_col = colors.pop(0)
print(first_col)
```

List length:

```# Find the length of a list
num_colors = len(colors)
print("We have " + str(num_colors) + " colors.")
```

Sorting a list:

```# Sorting a list permanently
colors.sort()
# Sorting a list permanently in reverse alphabetical order
colors.sort(reverse=True)
# Sorting a list temporarily
print(sorted(colors))
print(sorted(colors, reverse=True))
# Reversing the order of a list
colors.reverse()
```

Looping through a list:

```# Printing all items in a list
for col in colors:
print(col)
# Printing a message for each item, and a separate message afterwards
for col in colors:
print("Welcome, " + col + "!")
print("Welcome, we're glad to see you all!")
```

The range() function:

```# Printing the numbers 0 to 2000
for num in range(2001):
print(num)
# Printing the numbers 1 to 2000
for num in range(1, 2001):
print(num)
# Making a list of numbers from 1 to a million
nums = list(range(1, 1000001))
```

Simple statistics:

```# Finding the minimum value in a list
nums = [23, 22, 44, 17, 77, 55, 1, 65, 82, 2]
num_min = min(nums)
# Finding the maximum value
nums = [23, 22, 44, 17, 77, 55, 1, 65, 82, 2]
num_max = max(nums)
# Finding the sum of all numbers
nums = [23, 22, 44, 17, 77, 55, 1, 65, 82, 2]
total_num = sum(nums)
```

Slicing a list:

```# Getting the first three items
colors = ['Red', 'Blue', 'Green', 'Black', 'White']
first_three = colors [:3]
# Getting the middle three items
middle_three = colors[1:4]
# Getting the last three items
last_three = colors[-3:]
```

Copying a list:

```# Making a copy of a list
colors = ['Red', 'Blue', 'Green', 'Black', 'White']
copy_of_colors = colors[:]
```

List of Comprehensions:

```# Using a loop to generate a list of square numbers
squr = []
for x in range(1, 11):
sq = x**2
squr.append(sq)
# Using a comprehension to generate a list of square numbers
squr = [x**2 for x in range(1, 11)]
# Using a loop to convert a list of names to upper case
colors = ['Red', 'Blue', 'Green', 'Black', 'White']
upper_cols = []
for cols in colors:
upper_cols.append(cols.upper())
# Using a comprehension to convert a list of names to upper case
colors = ['Red', 'Blue', 'Green', 'Black', 'White']
upper_cols = [cols.upper() for cols in colors]
```

## Python: Tips of the Day

Simplify the way you collapse nested lists:

```x = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
]
x
```

Output:

```[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
```
```result = []
for sublist in x:
for item in sublist:
result.append(item)
result
```

Output:

```[1, 2, 3, 4, 5, 6, 7, 8, 9]
```
`[item for sublist in x for item in sublist]`

Output:

```[1, 2, 3, 4, 5, 6, 7, 8, 9]
```
```import itertools
itertools.chain(*x)
```

Output:

```<itertools.chain at 0x1dd5fb60320>
```
`list(itertools.chain(*x))`

Output:

```[1, 2, 3, 4, 5, 6, 7, 8, 9]
```
