2.Problem-solving ideas

1.How to Read a File

2.How do I get the code in the file

3.How do I remove symbols from my code

4.Design data structures to hold statistical results

3.Implementation process.

 4.Code description

4.1 Read the code in the file and remove symbols

while line:
    line = f.readline()
    line = line[:-1]
    line = line.replace("else if", "else-if")
    x = re.split(' |\(|\;|\\t|\:|\{|\/\/', line)
    for i in x:
        for j in range(kwd_len):
            if i == kwdlst[j]:
                if i == "switch":
                    num0s.append(num0)
                    num0 = 0
                if i == "case":
                    num0 += 1
                count[j] += 1
    for i in x:
        if i == "if" or i == "else" or i == "else-if":
            sentences.append(x)
            continue
f.close()

4.2 Statistics the total number of all keywords & Switch-case

for i in range(kwd_len):
    if count[i] != 0:
        sumres += count[i]
        if (i == 30):
            sumres += count[i]

4.3 Statistics of the if if-else if-else-if-else structure

for j in range(x_len):
    for i in sentences:
        if i[j] == "if":
            flag_if = 1
        if i[j] == "else-if":
            flag_else_if = 1
        if i[j] == "else":
            if flag_else_if == 1:
                num_if_else_if_else += 1
            elif flag_if == 1:
                num_if_else += 1
            flag_else_if = 0
            flag_else = 0

5.Test results

"D:\Program Files\Python38\python.exe" D:\worksapce\lab1-2\Lab2.py 
level of stastic (from 1 to 4): 4
sum :  35
switch  num :  2
case num [3, 2]
if-else num: 1
if-elseif-else num: 1

6.Summarize

In this assignment, I learned the combination of git and PyCharm and the importance of version control in code development, which laid a solid foundation for future code development.
