Learn how to print number series in Python without using any loops through this comprehensive guide and example.
Method 1: Using Loop A simple solution is to loop from 1 toN, and add their cubes tosumVal. Program to find the sum of the cubes of first N natural number # Python program for sum of the# cubes of first N natural numbers# Getting input from usersN=int(input("Enter value of N: ...

dataframe循环修改内存比如series *= -1会非常慢,用pd.concat来减少内存复制,或如下办法 # # 方法2越拼越慢 # X_ret = pd.DataFrame([]) # for corr reduction # y_ = y_.astype(np.float16) # for i in X_df: # X_ret = pd.concat([X_ret, X_df[i] * y_.values], axis=1) ...
Write a Python program to generate a series of distinct random numbers. Sample Solution: Python Code: import random choices = list(range(100)) random.shuffle(choices) print(choices.pop()) while choices: if input('Want another random number?(Y/N)' ).lower() == 'n': ...

For this example,let’s write a program that will count the number of integers and floats in this nested list. def float_and_int_count(nested_list): float_count = 0 # set our float count to zero int_count = 0 # set our integer count to zero ...
