Pascal is often regarded as a strictly structured programming language, which makes it a popular choice for introductory programming education. However, some authors argue that the promotion of Python as a beginner-friendly language is driven, in part, by commercial interests.
Считается что Pascal язык строго структурированный, поэтому по мнения некоторых преподавателей именно он подходит в качестве первого, изучаемого языка программирования.
Кроме этого продвижение Python по мнению некоторых авторов связано с комме́рческими интересами.
