python语法如何去除字符串最后的换行符

如何利用python语法去除字符串最后的换行符\n，下面web建站小编给大家简单介绍一下具体实现代码！

语法介绍：

s = s.replace('\n','').replace('\r','')

示例如下：

f = open('test.txt', 'r', encoding = 'UTF-8')
labelstr = f.readlines()
a = range(0,200)
index = [str(i) for i in a]
txt = [label.split(' ')[0].replace('\n','').replace('\r','') for label in labelstr]
labeldic = dict(zip(index, txt))

删除全部换行符

str1 = "\n Starbucks has the best coffee \n"
newstr = str1.strip()
print(newstr)
