print python variable with the variable name.

Project description

prina: print python variable with the variable name.

🦥 打印 Python 变量时,带着变量名称。

缘起

不知道你有没有这样的烦恼,在没有 IDE 的情况下做调试时,都会写一堆打印信息来查看数据是否准确。

比如:

a = "1"
b = 2
c = True
print(a, b, c)
# 1 2 True

如果直接这样打印,在控制台的输出中就很难区分不同变量的值。

因此需要安装下面的方式来书写,其中就有很多变量名需要写两遍。

a = "1"
b = 2
c = True
print("a: {} b: {} c: {}".format(a, b, c))
# or (Python3.6+ 支持的语法)
print(f"a: {a} b: {b} c: {c}")
# a: 1 b: 2 c: True

那么有没有一种方法可以打印 Python 变量时,带着变量名称呢?

我找了半天 Python 的内置函数,发现都无法完成这一功能,于是就有了 prina 这个库。

prina = print + name

使用方法

from prina import prina

a = "1"
b = 2
c = True

prina(a, b, c)
# a: 1 b: 2 c: True

其他

Python 3.8 中,你可以使用 f-string 来调试文档:

a = "1"
b = 2
c = True

print(f"{a=} {b=} {c=}")
# a=1 b=2 c=True
