In this tutorial we will see how can we check in Python if a given number is a perfect square or not without using the sqrt function in Python.
In order to avoid thisTraceback Error, we can use the keywordinto check if a substring is contained in a string. In the case of Loops, it was used for iteration, whereas in this case it’s a conditional that can be eithertrueorfalse.It’ll be true if the substring is part of the ...
Python code to check whether a number is a power of another number or not# importing the module import math # input the numbers a, b = map(int, input("Enter two values: ").split()) s = math.log(a, b) p = round(s) if (b**p) == a: print("{} is the power of anot...
# Python program to calculate square of a number # Method 1 (using number*number) # input a number number = int (raw_input ("Enter an integer number: ")) # calculate square square = number*number # print print "Square of {0} is {1} ".format (number, square) ...

(c): # take the square root of a complex number, return a complex number rad = arctan(c[1]/c[0]) # range from -pi/2 to pi/2 # rad should be from -pi to pi if c[0]>0 and c[1]>0: rad = rad elif c[0]>0 and c[1]<0: rad = rad elif c[0]<0 and c[1]>0...
Python 在语法上是编程语言中独一无二的,因为它使用空白或缩进块来屏蔽代码。像 C 这样的语言用花括号括起了一个代码块,比如一个if语句;Python 使用冒号和缩进来描述块。C 语言中的代码如下所示:if (x==4) { printf("x is equal to four\n"); printf("Nothing more to do here.\n"); } printf(...

In other words, you may need to check if a given value is or is not a member of a collection of values. Python calls this kind of check a membership test. Note: For a deep dive into how Python’s membership tests work, check out Python’s “in” and “not in” Operators: Check...
Python provides us with differentstring methodswith which we can check if a string contains a number or not. Theisnumeric()method, when invoked on a string, returnsTrueif the string consists of only numeric characters. If the string contains non-numeric characters, it returnsFalse. ...
