str = "Line1-abcdef \nLine2-abc \nLine4-abcd";
print (str.split( ))       # 以空格为分隔符，包含 \n  ['Line1-abcdef', 'Line2-abc', 'Line4-abcd']
print (str.split(' ', 1 )) # 以空格为分隔符，分隔成两个 ['Line1-abcdef', '\nLine2-abc \nLine4-abcd']

txt = "Google#Runoob#Taobao#Facebook"
# 第二个参数为 1，返回两个参数列表
z = txt.split("#")
print(z)  #['Google', 'Runoob', 'Taobao', 'Facebook']
x = txt.split("#", 1)
print(x)  #['Google', 'Runoob#Taobao#Facebook']
