value_list = ["apple"] boolean_series = df.fruit.isin(value_list) filtered_df = df[boolean_series]
Here is what the above code is Doing:
1. Create a list of values that we want to filter by.
2. Create a boolean series that is True when the value is in the list.
3. Use the boolean series to filter the dataframe.
stats = Stats() >>> stats.network = ‘BW’ >>> print(stats[‘network’]) BW >>> stats[‘station’] = ‘MANZ’ >>> print(stats.station) MANZ Here is what the above code is Doing: 1. Create a Stats object. 2. Set the network attribute to ‘BW’. 3. Print the network attribute. 4. Set the station attribute to ‘MANZ’. 5. Print the station attribute. The…
class Person: def __init__(self, _name, _age): self.name = _name self.age = _age def sayHi(self): print(‘Hello, my name is ‘ + self.name + ‘ and I am ‘ + self.age + ‘ years old!’) p1 = Person(‘Bob’, 25) p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old! Here is what the…
>>> keys = [2,3,10] >>> vals = [7,9,11] >>> dict(zip(keys, vals)) {2: 7, 3: 9, 10: 11} Here is what the above code is Doing: 1. zip() takes two lists and creates a list of tuples, where the first item in each passed list is paired together, and then the second item in each passed…
import os os.startfile(‘C:\\Path\\To\\file.docx’) Here is what the above code is Doing: 1. os.startfile() is a function that opens a file in its default program. 2. ‘C:\\Path\\To\\file.docx’ is the path to the file you want to open. 3. The path is a string, so it needs to be enclosed in quotes. 4. The path uses double…
#Returns the last 10 rows of the df df.tail(10) Here is what the above code is Doing: 1. We’re importing the pandas library and giving it the alias pd. 2. We’re importing the numpy library and giving it the alias np. 3. We’re importing the matplotlib library and giving it the alias plt. 4. We’re…
import os import sys restart = input(“\nDo you want to restart the program? [y/n] > “) if restart == “y”: os.execl(sys.executable, os.path.abspath(__file__), *sys.argv) else: print(“\nThe program will be closed…”) sys.exit(0) Here is what the above code is Doing: 1. It’s asking the user if they want to restart the program. 2. If the user enters…
