问题 This question already has answers here : How do I modify a single character in a string, in Python? (4 answers) Closed 2 years ago . I want to randomly capitalize or lowercase each letter in a string. I'm new to working with strings in python, but I think because strings are immutable that I can't do the following: i =0 for c in sentence: case = random.randint(0,1) print("case = ", case) if case == 0: print("here0") sentence[i] = sentence[i].lower() else: print("here1") sentence[i] = sentence

问题 This question already has answers here : Lambda Expression in Powershell (3 answers) Closed last year . I am writing a powershell script to parse the HTM file. I need to find all the links file in the file and then uppercase the filepath, filename and extention. (could be 30 or 40 links in any file). The part I'm having trouble with is the 2nd part of the -replace staement below (the 'XXXX' part). The regex WILL find the strings I'm looking for but I can't figure out how to 'replace' that

问题 I am trying to check a string for any Uppercase letter. my code shows NO UPPER for any input, may it be "sss", "Sss", "SSS" if [[ "$pass" =~ [^a-zA-Z0-9] ]] then echo "Upper found" else echo "no upper" fi 回答1: [^a-zA-Z0-9] means anything except for a-z , i.e. lowercase letters, A-Z , i.e. uppercase letters, and 0-9 , i.e. digits. sss , Sss , SSS all contain just letters, so they can't match. [[ $password =~ [A-Z] ]] is true if the password contains any uppercase letter. You should set LC_ALL

问题 I am pretty new to python and sqlalchemy and would like to ask for an advice. What would be the best way to force uppercase values in a SqlAlchemy field when the record is inserted/updated? Should I use events for that? Here I am using flask-sqlalchemy version, but I believe it is something similar to SQLAlchemy. from flask.ext.sqlalchemy import SQLAlchemy db = SQLAlchemy() class Item(db.Model): # I need to ensure the code column converts values to uppercase automatically code = db.Column(db
