Python 中打印金字塔技术的程序

2024 年 8 月 29 日 | 阅读 3 分钟

Python 提供基本的 for 循环来打印模式。第一个外部循环控制行数，内部嵌套循环控制列数。通过修改 print 语句，可以打印新的数字模式、单词模式和星形模式。

本文说明了其中的一些模式。

1. 简单金字塔模式

# Python 3.x code for star pattern demonstration Printing pattern demonstration #function
def pypart(a):
    # outer loop in this case to manage the number of rows
    for i in range(0, a):
        # Inner loop to manage values changing according to the outer loop's number # of columns.
        for j in range(0, i+1):
            # printing up stars
            print("* ",end="")
        # final line following each row
        print("\r")
# Driver Code
a = 5
pypart(a)

输出

* 
* * 
* * * 
* * * * 
* * * * *

2. Python 3 的 List 功能将使此过程更简单。

# Star pattern demonstration in Python 3.x # Displays a printing pattern in action
def pypart(a):
    myList1 = []
    for i in range(1, a+1):
        myList.append("*"*i)
    print("\n".join(myList1))
# Driver Code
a = 5
pypart(a)

输出

*
**
***
****
*****

3. 递归方法

# Pyramid pattern printing in Python 3 using recursion
def pypart(a):
	if a == 0:
		return
	else:
		pypart(a-1)
		print("* "*a)
# Driver Code
n = 5
pypart(n)

输出

* 
* * 
* * * 
* * * * 
* * * * *

4. 使用 While 循环

# Pyramid pattern printing in Python 3 with while loop
a=5
i=1; j=0
# Until the condition becomes false in the while loop, the condition is checked. # If it is true, enter the loop & print the pattern.
while(i<=a):
    while(j<=i-1):
        print("* ",end="")
        j+=1
     # printing the subsequent row's line
    print("\r")
    j=0;i+=1

输出

* 
* * 
* * * 
* * * * 
* * * * *

5. 180 度旋转法

# Star pattern demonstration in Python 3.x # Displays a printing pattern in action
def pypart2(a):
    # number of spaces
    s = 2*s - 2
    # row count is handled by an outer loop.
    for i in range(0, a):
# inner loop for handling number spaces and changing values in accordance with # requirements
        for j in range(0, s):
            print(end=" ")
        # decrementing s after each loop
        s = s - 2
        # Inner loop to handle the amount of columns and any values that change 
# according to the outer loop.
        for n in range(0, m+1):
            # printing up stars
            print("* ", end="")
        # ending up the line after each row
        print("\r")
# Driver Code
a = 5
pypart2(a)

输出

        * 
      * * 
    * * * 
  * * * * 
* * * * *

6. 打印三角形

# Star pattern demonstration in Python 3.x 
# Triangle serving as an example of a printing pattern
def triangle(s):
	# Number of spaces to be noted
	a = b - 1
	# Outer loop to handle number of rows
	for m in range (0, b):
		# inner loop to handle number spaces
		# values changing acc. to requirement
		for n in range(0, a):
			print(end=" ")
		# decrementing a after each loop
		a = a - 1
# To handle the number of columns and the changing values according to the
 # outer loop, use an inner loop.
		for n in range(0, m+1):
			# printing up the stars
			print("* ", end="")
		# ending the line after each the row
		print("\r")
# Driver Code
b = 5
triangle(b)

输出

   * 
   * * 
  * * * 
 * * * * 
* * * * *

7. 数字模式

# Star pattern demonstration in Python 3.x Function to display the number 
def numpat(s):	
	# Initialising of starting number
	num = 1
	# outer loop to be handle number of rows
	for m in range(0, n):
		# re assigning num1
		Num1 = 1
		# inner loop to be handled  at number of columns
		# values changing to acc. to outer loop
		for n in range(0, m+1):	
				# printing up number
			print(num1, end=" ")
			# incrementing the number at each column
			Num1 = num1 + 1
		# ending up line after each row
		print("\r")
# Driver code
s = 5
numpat(s)
