How to split string before a character then have python create a list from it [duplicate]-CodePudding

I am trying to make python take a string, separate the characters before another character eg: "10001001010Q1002000293Q100292Q". I want to separate the string before each Q and have python create either a list or another string. I cannot figure this out for the life of me.

CodePudding user response：

You can do this using the split function, give "Q" as a parameter to the split function then you can slice the list to only get the numbers before Q.

num = "10001001010Q1002000293Q100292Q"
print(num.split("Q")[:-1])

Split() function: https://www.w3schools.com/python/ref_string_split.asp

The syntax is str.split("separator").

str = str.split("Q")

Then output will be ['10001001010', '1002000293', '100292', '']. If you don't need the last empty element then you can write as:

str = str.split("Q")[:-1]
