How to set font color in Latex (3 ways)

Leave a reply

1. Use the defined color directly
\usepackage{color}

\textcolor{red/blue/green/black/white/cyan/magenta/yellow}{text}

where textcolor{…} contains the system-defined colors

 

2. Combine the values of red, green and blue to form the color we want
\usepackage{color}

\textcolor[rgb]{r,g,b}{text}

where {r,g,b} represents the combination of red, green and blue colors, and takes values in the range [0-1]

\textcolor[RGB]{R,G,B}{text}

where {R,G,B} represents the combination of red, green and blue colors, and the range of values is [0-255]

 

3. Define a color, call directly
\usepackage{color}

\definecolor{ColorName}{rgb}{r,g,b} This time r/g/b is defined in the range [0-1].

\definecolor{ColorName}{RGB}{R,G,B}, when the domain of R/G/B is defined in [0-255].

Here the name ColorName is defined for the color, and the following can call this color scheme directly

\textcolor{ColorName}{text}

PHP: How to get the total number of data in the MySQL table (total number of rows)

RewCount (): Returns the number of rows affected:

 $sql='select * from '.$_POST['fname'].'_blog_data';
		 $sth=$pdo->query($sql);
		 die('<script>alert('.$sth->rowCount().')</script>');

2

$q = $pdo->query("SELECT count(*) from w_login_record;"); $rows = $q->fetch(); $rowCount = $rows[0];
		 die('alter("'.$rowCount.'")');

3

Use the fetchAll function $q = $db->query("SELECT ..."); $rows = $q->fetchAll(); $rowCount = count($rows);

ValueError: need more than 1 value to unpack

class Person():

def __init__(self, Newname, Newage, Newtype):

self. type = Newtype,self.name = Newname,self. age = Newage,

This is the wrong way to write, not on the same line!

#     def __init__(self, Newname,Newage,Newtype):

#         self.name = Newname,

#         self. age = Newage,

#         self. type = Newtype,

from django. http import  HttpResponse
from django. template import Template ,Context
import datetime
from HelloDjango.Model. Person import *

def Hello(request , offset ):

tempStr = “{{person.name}} {{person. age}} {{person. type}}”
tempAnswer = {“person” : Person(“hjc”, “11”, “man”)}
#
#     tempStr = “{{person.name}} {{person. age}} {{person. type}}”
#     tempAnswer = {“person” : Person(‘hjc’ , ’11’ ,’man’)}

t = Template(tempStr)
c = Context(tempAnswer)
return HttpResponse(t.render(c))

No artifacts package solution for idea to configure Tomcat

I don’t know why my idea is always inexplicably wrong, maybe it is aimed at me
1. At this point you can see that there are no artifacts and there are warnings in the bottom that cause Tomcat to not be successfully configured

2. The solution I found on the Internet is to check this box, but my default is that the box does not solve my problem
 

3. I updated the Maven environment and solved it successfully

Conclusion: Just update the Maven environment
 

The reason and solution of the error of join function: sequence item 0: expected STR instance, int found

When I was writing code the other day, the task was to separate the incoming parameters with “_” and then append them to the file
Direct up code

def operate(file_path, *args):
    f = open(file_path, mode="a", encoding="utf-8")
    s = ""
    s = '_'.join(args)
    f.write(s)
    f.flush()
    f.close()
operate("hhhh.txt", 123, 456, 789)

Receive a string, but I wrote a number by mistake, then reported an error
TypeError: sequence item 0: expected STR instance, int found TypeError: sequence item 0: expected STR instance, int found TypeError: sequence item 0: expected STR instance, int found
Then look for the document, and here’s the original text
Return a string which is the concatenation of the strings in iterable. A TypeError will be raised if there are any non-string values in iterable, including bytes objects. The separator between elements is the string providing this method.
The join function is a string function, and the arguments and inserts are strings
So:
S = ‘_’.join(args) to

s = '_'.join(str(args).strip())

That’s it!
 
 
 

Type error: sequence item 0: expected STR instance, int found

TypeError: sequence item 0: expected STR instance, int found TypeError: sequence item 0: expected STR instance, int found
List1 =[1,’two’,’three’,4]
print(‘ ‘.join(list1))
I thought it would print 1, two, three, four
The result was an error
Traceback (most recent call last):
File “< pyshell#27>” , line 1, in < module>
print(” “.join(list1))
peerror: sequence item 0: expected STR instance, int found
p> (“.join(list1))
TypeError: sequence item 0: expected STR instance, int found
A list of numbers cannot be converted directly to a string.
Print (” “.join(‘%s’ %id for id in list1))
That is, iterating through the elements of the list, converting them to strings. So I can print 1, 2, 3, 4.
