python格式化文本_如何在Python中格式化文本,就像在Illustrator中一样？

有可能提出棘手的解决方案,考虑单声道间隔字体,可以解决您的问题.但他们只是等着失败.您帖子中的灰色列可以完全按照图中的颜色添加,但我选择不改变字母中的颜色(因为我发现它更具可读性).

PIL可以提供以下内容：

略微改变字体：

接下来会有更“严重”的字体更改,所有字体都按原样生成.

接下来是生成这些数字的代码.我并没有真正做到这一点,它可以在很多方面得到改善.将此视为您需要做的事情的一个示例,可能会为您的问题找到解决方案.要使用任何类型的字体,您需要一个实际的排版系统,例如LaTeX.

# format.

line4 = [("Wave 1:",("_XXXX_X____X_X_",0)]

line5 = [("Wave 2:",("__XX_XXX_X__X_X",0)]

# Texts to draw over the last element,in specific positions,# of lines present in line_data.

subscript = {

2: { # Meaning: third item in line_data

0: "170",# Meaning: draw "170" over the first char

len(line3[-1][0]) - 1: "185",# Draw "185" over the last char

7: "180",# Meaning: draw "180" over the eight char

},4: {5: "hi"},3: {6: "ops"}
