# You can use sum directly after indexing with indices: a = np.array([1,2,3,4]) indices = [0, 2] a[indices].sum() # Result: 4
Here is what the above code is Doing:
1. a[indices] returns the array [1, 3]
2. .sum() sums the array
3. The result is 4

df.groupby(‘param’)[‘column’].nunique().sort_values(ascending=False).unique().tolist() Here is what the above code is Doing: 1. We’re grouping by the ‘param’ column and counting the number of unique values in the ‘column’ column. 2. We’re sorting the values in ascending order and selecting the first value. 3. We’re converting the result to a list.
import os os.system(‘tzutil /s “Central Standard Time”‘) //In windows command prompt try: //This gives current timezone: tzutil /g //This gives a list of timezones: tzutil /l //This will set the timezone: tzutil /s “Central America Standard Time” Here is what the above code is Doing: 1. It’s getting the current timezone. 2. It’s getting a…
def build_matrix(rows, cols): matrix = [] for r in range(0, rows): matrix.append([0 for c in range(0, cols)]) return matrix if __name__ == ‘__main__’: build_matrix(6, 10) Here is what the above code is Doing: 1. We start by creating an empty list called matrix. 2. We then use a for loop to iterate through each row…
print(“This is where you put the message you want to write”) Here is what the above code is Doing: 1. It’s creating a new file called “my_file.txt” 2. It’s opening the file in write mode 3. It’s writing the message “This is where you put the message you want to write” to the file 4….
x = input(“Input Your Name”) #lets say I input Bob print(x) #It should output Bob Here is what the above code is Doing: 1. It’s asking for input 2. It’s storing the input in a variable called x 3. It’s printing the variable x
