4 python split function python-3.x difference
我用的split()
是and,rsplit()
如下图:
test = "1--2--3--4--5"
print(test.split("--")) # Here
print(test.rsplit("--")) # Here

然后,我得到了相同的结果,如下所示:
['1', '2', '3', '4', '5'] # split()
['1', '2', '3', '4', '5'] # rsplit()

没有参数,如下所示:
test = "1 2 3 4 5"

他们可以将字符串除以一个或多个空格,如下所示:
['1', '2', '3', '4', '5'] # split()
['1', '2', '3', '4', '5'] # rsplit()

并且,只有str
类型有split()
and,rsplit()
如下所示:
test = ["1 2 3 4 5"] # Doesn't have split()
print(test.split()) # Error
