It can often be useful to evaluate the length of a string. The built-in function len() returns the length of a string:Python Copy s = 'supercalifragilisticexpialidocious' len(s) The output is:Output Copy 34 Another useful built-in function for working with strings is str(). This ...
def function(*args): x = [] y = 0 for i in range(len(args)): x.append(args[y]) y += 1 x = list(map(float, x)) return sum(x) Run Code Online (Sandbox Code Playgroud) 有没有办法以其他方式执行此操作,不使用"for i"循环并且更有效? python indexing list python-3.x Gus*...
>>> import numpy as np >>> arr=np.arange(12).reshape(2,2,3) >>> print(arr[0:3]) [[[ 0 1 2] [ 3 4 5]] [[ 6 7 8] [ 9 10 11]]] >>> print(arr[1:5:2,::3]) [[[6 7 8] Conclusion This was in brief about array indexing in the Python programming language. Ho...
Let us see how to slice an array between indexes − importnumpyasnp a=np.arange(10)print("Array from index 1 to 6:",a[1:7]) When we run above program, it produces following result − Array from index 1 to 6: [1 2 3 4 5 6] ...
