Disk drill mac review. In this Python cheat sheet, we will walk you through a couple of examples using two of the most used data types: the list and the Pandas DataFrame. The list is self-explanatory; it's a collection of values set in a one-dimensional array. A Pandas DataFrame is just like a tabular spreadsheet, it has data laid out in columns and rows.
Let's take a look at a few neat things we can do with lists and DataFrames in Python!

Python Cheat Sheet
Lists
Creating Lists
Create an empty list and use a for loop to append new values.
#add two to each value
my_list = []
for x in range(1,11):
my_list.append(x+2)
We can also do this in one step using list comprehensions:
my_list = [x + 2 for x in range(1,11)]
Creating Lists with Conditionals
As above, we will create a list, but now we will only add 2 to the value if it is even.
#add two, but only if x is even
my_list = []
for x in range(1,11):
if x % 2 0:
my_list.append(x+2)
else:
my_list.append(x)
Using a list comp:
my_list = [x+2 if x % 2 0 else x
for x in range(1,11)]
White Buttercup's botanical name is Beesia, and it's a fantastic shade-loving ground cover. It makes a great filler for woodland gardens, and really, anywhere you can't get. White Buttercup - (Oenothera pallida) Perennial Plants Other Common Names: Evening Primrose, Pale Evening Primrose, Oenothera Pallida Var. Runcinata, Oenothera Runcinata Family: Onagraceae Genus: Oenothera Species: pallida. White buttercup squash.
Selecting Elements and Basic Stats
Select elements by index.
#get the first/last element
first_ele = my_list[0]
last_ele = my_list[-1]
Python 3 Quick Reference Card
Some basic stats on lists:
#get max/min/mean value
biggest_val = max(my_list)
smallest_val = min(my_list)avg_val = sum(my_list) / len(my_list)
DataFrames
Reading in Data to a DataFrame
We first need to import the pandas module.
import pandas as pd
Then we can read in data from csv or xlsx files:
df_from_csv = pd.read_csv(‘path/to/my_file.csv',
sep=',',
nrows=10)
xlsx = pd.ExcelFile(‘path/to/excel_file.xlsx')
df_from_xlsx = pd.read_excel(xlsx, ‘Sheet1')
Slicing DataFrames
We can slice our DataFrame using conditionals.
df_filter = df[df[‘population'] > 1000000]
df_france = df[df[‘country'] ‘France']
Sorting values by a column:
df.sort_values(by='population',
ascending=False)
Filling Missing Values
Let's fill in any missing values with that column's average value.
df[‘population'] = df[‘population'].fillna(
value=df[‘population'].mean()
)
Applying Functions to Columns
Apply a custom function to every value in one of the DataFrame's columns.
def fix_zipcode(x):
''
make sure that zipcodes all have leading zeros
''
return str(x).zfill(5)
df[‘clean_zip'] = df[‘zip code'].apply(fix_zipcode)
