Python program to search for a pattern in stringn=int(input("Enter number of cities : ")) city=() for i in range(n): c=input("Enter City : ") city+=(c,) print(city) pat=input("Enter Pattern you want to search for? ") for c in city: if(c.find(pat)!=-1): print(c)...
On the other hand, if the condition becomes false, then assert halts the program by raising an AssertionError.In Python, assert is a simple statement with the following syntax:Python assert expression[, assertion_message] Here, expression can be any valid Python expression or object, which is...
You can use that function to do a binary search in Python in the following way: Python import math def find_index(elements, value): left, right = 0, len(elements) - 1 while left <= right: middle = (left + right) // 2 if math.isclose(elements[middle], value): return middle if...
c. import Python: 这个命令会报错,因为Python不是一个模块名。import语句后面要跟有效的模块名,用于导入该模块中定义的函数、类或变量。 d. import Zen: 这个命令会报错,因为没有这个模块。Zen是Python之禅的内容,不是一个Python模块。 我们理解一下python命令 Python 命令是指在命令行界面下直接运行 Python ...
本文实例讲述了Python3中正则模块re.compile、re.match及re.search函数用法。分享给大家供大家参考,具体如下: re模块 re.compile、re.match、 re.search 正则匹配的时候,第一个字符是 r,表示 raw string 原生字符,意在声明字符串中间的特殊字符不用转义。
