如何在Python中将彩色文本输出到终端?
当前回答
这里有一个简单的函数,我使用它来打印彩色文本消息,而不必记住ANSI代码,而是使用标准RGB元组来定义前景和背景颜色。
def print_in_color(txt_msg, fore_tuple, back_tuple, ):
# Prints the text_msg in the foreground color specified by fore_tuple with the background specified by back_tuple
# text_msg is the text, fore_tuple is foreground color tuple (r,g,b), back_tuple is background tuple (r,g,b)
rf,bf,gf = fore_tuple
rb,gb,bb = back_tuple
msg = '{0}' + txt_msg
mat = '\33[38;2;' + str(rf) + ';' + str(gf) + ';' + str(bf) + ';48;2;' + str(rb) + ';' +str(gb) + ';' + str(bb) + 'm'
print(msg .format(mat))
print('\33[0m') # Returns default print color to back to black
# Example of use using a message with variables
fore_color = 'cyan'
back_color = 'dark green'
msg = 'foreground color is {0} and the background color is {1}'.format(fore_color, back_color)
print_in_color(msg, (0,255,255), (0,127,127))

下面是一个可以这样使用的实现:
from stryle import Stryle
print(Stryle.okgreen.bold@"Hello World" + Stryle.underline@'!' + ' back to normal')
print(f"{Stryle.red}Merry {Stryle.underline.okgreen}Christmas!{Stryle.off}")
print("Merry "@Stryle.red + "Christmas"@Stryle.okgreen.underline)
_decorations = {
"header" : '\033[95m',
"okblue" : '\033[94m',
"okcyan" : '\033[96m',
"okgreen" : '\033[92m',
"yellow" : '\033[93m',
"red" : '\033[91m',
"warning" : '\033[93m',
"fail" : '\033[91m',
"off" : '\033[0m',
"bold" : '\033[1m',
"underline" : '\033[4m',
}
class _StringStyle(str):
def __getattribute__(self, decoration: str = _decorations["off"]):
if decoration in _decorations:
return _StringStyle(self.decorations + _decorations[decoration])
return self
def __matmul__(self, other):
return self.decorations + str(other) + _decorations["off"]
def __rmatmul__(self, other):
return self.decorations + str(other) + _decorations["off"]
def __str__(self):
return self.decorations
Stryle = _StringStyle()
试试这个简单的代码
def prRed(prt):
print(f"\033[91m{prt}\033[00m")
def prGreen(prt):
print(f"\033[92m{prt}\033[00m")
def prYellow(prt):
print(f"\033[93m{prt}\033[00m")
def prLightPurple(prt):
print(f"\033[94m{prt}\033[00m")
def prPurple(prt):
print(f"\033[95m{prt}\033[00m")
def prCyan(prt):
print(f"\033[96m{prt}\033[00m")
def prLightGray(prt):
print(f"\033[97m{prt}\033[00m")
def prBlack(prt):
print(f"\033[98m{prt}\033[00m")
def prReset(prt):
print(f"\033[0m{prt}\033[00m")
prGreen("Hello, Green World!")
prBlack("Hello, Black World!")
prCyan("Hello, Cyan World!")
prGreen("Hello, Green World!")
prLightGray("Hello, Light Grey World!")
prLightPurple("Hello, Light Purple World!")
prPurple("Hello, Purple World!")
prRed("Hello, Red World!")
prYellow("Hello, Yellow World!")
prReset("Hello, Reset World!")
Python 3示例
# python2
def prRed(prt): print("\033[91m {}\033[00m" .format(prt))
def prGreen(prt): print("\033[92m {}\033[00m" .format(prt))
def prYellow(prt): print("\033[93m {}\033[00m" .format(prt))
def prLightPurple(prt): print("\033[94m {}\033[00m" .format(prt))
def prPurple(prt): print("\033[95m {}\033[00m" .format(prt))
def prCyan(prt): print("\033[96m {}\033[00m" .format(prt))
def prLightGray(prt): print("\033[97m {}\033[00m" .format(prt))
def prBlack(prt): print("\033[98m {}\033[00m" .format(prt))
prGreen("Hello, World!")
对于Windows,除非使用Win32 API,否则无法使用颜色打印到控制台。
对于Linux,它就像使用打印一样简单,转义序列如下:
颜色
要使字符像方框一样打印,这实际上取决于控制台窗口使用的字体。磅符号效果很好,但它取决于字体:
#
class ColorText:
"""
Use ANSI escape sequences to print colors +/- bold/underline to bash terminal.
Examples
--------
>>> ColorText('HelloWorld').bold()
>>> ColorText('HelloWorld').blue()
>>> ColorText('HelloWorld').bold().custom("#bebebe")
>>> ColorText('HelloWorld').underline().custom('dodgerblue')
>>> ColorText.demo()
Notes
-----
- execute ColorText.demo() for a printout of colors.
